Death in Police Custody: Documentation Standards and Case Laws in India

1. Introduction

Death in police custody is one of the most serious forms of alleged custodial violence because a person who is deprived of liberty remains under the direct control and responsibility of the State. The constitutional foundation of the documentation and investigation process is principally Article 21 of the Constitution, which protects life and personal liberty, together with Article 22 and the statutory safeguards governing arrest, detention, inquest and investigation.

Under the present criminal-procedure framework, the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) is especially important. Section 196 BNSS specifically requires a Magistrate's inquiry where a person dies or disappears while in police custody or other custody authorised by a Magistrate or Court.

Documentation is not merely an administrative formality. It serves several purposes:

preserving evidence;

preventing manipulation of the cause of death;

identifying injuries and their timing;

establishing the chain of custody;

enabling an independent investigation;

protecting the deceased's family;

facilitating judicial scrutiny; and

determining civil, criminal and constitutional liability.

2. Statutory framework

A. Article 21 — Right to life and personal liberty

Article 21 protects every person, including an arrested or detained person.

Custody does not extinguish constitutional rights. The State assumes a heightened responsibility for the safety and dignity of a person whom it has deprived of liberty.

The Supreme Court's custodial-death jurisprudence therefore treats unexplained death in custody as a matter requiring particularly careful scrutiny.

3. Section 194 BNSS — Police inquiry into cause of death

Section 194 BNSS deals with inquiries into the cause of death in circumstances requiring police investigation/inquest.

The police documentation should ordinarily establish:

identity of the deceased;

date, time and place of death;

circumstances in which the person became unconscious or died;

place and duration of custody;

officers/personnel responsible for custody;

condition of the deceased before custody;

condition immediately before death;

injuries observed;

treatment provided;

witnesses present;

relevant documents and records; and

circumstances suggesting accident, suicide, natural death or custodial violence.

The police inquest, however, does not replace the mandatory Magistrate inquiry in a custodial death.

4. Section 196 BNSS — Mandatory Magistrate's inquiry

This is one of the most important provisions.

Section 196(2) BNSS provides that where a person dies or disappears while in police custody, or where the specified custodial sexual-offence situation arises, an inquiry shall be conducted by the Magistrate having local jurisdiction, in addition to the police investigation.

Section 196 further provides important procedural safeguards.

Important documentation requirements

The Magistrate's inquiry should preserve:

statements/evidence collected;

circumstances surrounding the death;

medical evidence;

post-mortem documentation;

relevant police records;

information concerning relatives;

relevant electronic evidence; and

other material necessary to determine the cause and circumstances of death.

Where practicable, relatives whose names and addresses are known should be informed and allowed to remain present during the inquiry.

Section 196(6) further requires the body, within 24 hours of death, to be forwarded for medical examination to the nearest Civil Surgeon or other qualified medical practitioner appointed by the State Government, unless this is impracticable for recorded reasons.

5. Post-mortem examination

The post-mortem examination is central to documentation in a custodial-death case.

The examination should be sufficiently detailed to determine:

external injuries;

internal injuries;

fractures;

soft-tissue injuries;

ligature marks;

restraint marks;

burns;

blunt-force trauma;

signs of poisoning;

signs of asphyxia;

disease or natural pathology;

approximate time since death;

whether injuries are ante-mortem or post-mortem;

possible mechanism of death; and

whether medical treatment could have prevented death.

The NHRC has specifically issued a revised format for post-mortem examinations in cases of death in police custody, along with instructions concerning submission of post-mortem reports.

6. Videography and photography

Visual documentation is particularly important because injuries may disappear or change after death.

The NHRC's guidelines specifically provide for photography and video-filming of post-mortem examinations in cases of death in police action. The photographs and video are to be preserved and transmitted as required by the applicable procedure.

The NHRC continues to list separate guidance concerning:

post-mortem examination;

videography;

magisterial inquiry;

custodial deaths; and

submission of reports.

Practical documentation standard

The video should, as far as applicable:

identify the deceased;

record the condition of the body before examination;

show relevant external injuries;

record the examination systematically;

document internal findings where appropriate;

identify samples collected;

record the sealing of samples;

preserve the original digital file; and

maintain a documented chain of custody.

7. Photographic documentation

Photographs should preferably document:

A. Full-body photographs

front;

back;

right side;

left side.

B. Injury photographs

Each significant injury should be photographed:

before cleaning;

with sufficient lighting;

with a measurement scale where appropriate;

from an appropriate distance; and

in close-up detail.

C. Identification

Photographs should be linked to the deceased and the post-mortem documentation so that there is no uncertainty concerning identity.

8. Medical records

The deceased's complete medical history during custody should be preserved.

This can include:

medical examination at the time of arrest;

subsequent periodic medical examinations;

injury reports;

hospital referral documents;

emergency-room records;

prescriptions;

diagnostic reports;

nursing records;

treatment charts;

medication records;

ambulance records;

hospital admission/discharge records; and

death certificate/medical cause-of-death certificate.

A major evidentiary question in custodial death cases is often:

What was the physical condition of the person when custody began, and what changed during custody?

Consequently, the initial medical examination is extremely important.

9. Arrest and custody documentation

The Supreme Court's decision in D.K. Basu v. State of West Bengal, AIR 1997 SC 610 is foundational.

The Court laid down safeguards concerning arrest and detention, including:

identification of police officers;

preparation of an arrest memo;

attestation of the arrest memo;

informing a relative/friend;

diary entries;

recording injuries;

medical examination;

forwarding relevant documents to the Magistrate;

access to counsel during interrogation; and

communication to police control rooms.

These safeguards were designed specifically to reduce the possibility of custodial torture and death.

Importance for death documentation

If a person enters custody apparently healthy but later dies with multiple injuries, the following documents become crucial:

Arrest record → initial medical examination → custody diary → interrogation record → CCTV → subsequent medical examination → hospital record → post-mortem → forensic reports.

The integrity of this chronological chain can determine the reliability of the investigation.

10. CCTV documentation

The Supreme Court's judgment in Paramvir Singh Saini v. Baljit Singh, (2021) 1 SCC 184 is extremely important.

The Court directed installation and functioning of CCTV systems in police stations and specified extensive coverage requirements. The directions included areas such as:

entry and exit points;

main gate;

lock-ups;

corridors;

reception/lobby;

police-station rooms;

areas outside lock-ups; and

other relevant areas.

The CCTV system was required to have audio and video capabilities, with safeguards concerning preservation and oversight.

The Court also required oversight mechanisms to review footage for possible human-rights violations.

Why CCTV matters in custodial death cases

CCTV can establish:

when the detainee entered custody;

physical condition;

movements within the station;

persons entering the lock-up;

interrogation activity;

medical emergencies;

requests for medical treatment;

removal to hospital;

time of collapse; and

circumstances immediately preceding death.

The absence, destruction, malfunction or unexplained loss of relevant CCTV footage can therefore become a significant investigative issue.

A 2024 Supreme Court proceeding concerning CCTV compliance reiterated that the mandate in Paramvir Singh Saini must be implemented in letter and spirit.

11. Electronic evidence preservation

A modern custodial-death investigation should not be limited to paper records.

Relevant electronic evidence may include:

CCTV footage;

body-camera footage, where available;

police-station access-control logs;

call-detail records;

GPS/location records;

police vehicle GPS;

emergency-call records;

wireless/radio communications;

mobile-phone data;

hospital CCTV;

electronic medical records; and

computerised station diaries.

The original data should be preserved rather than relying solely upon screenshots or edited clips.

A proper chain of custody should record:

Who collected → when collected → from what device → how copied → hash/value where appropriate → where stored → who accessed it → when transferred.

12. Police station diary and custody register

The station diary/general diary and custody records should be examined for:

exact time of arrest;

arrival at police station;

departure from station;

movements;

interrogation;

meals/water;

medical complaints;

injuries;

visits by officers;

production before Magistrate;

hospital transfer;

return from hospital;

collapse;

emergency response; and

death.

An unexplained discrepancy between the official custody record and independent evidence can become significant.

13. Chain of custody of physical evidence

Every physical exhibit should be documented.

Examples include:

clothing;

footwear;

bedding;

restraints;

ropes/ligatures;

blood-stained articles;

biological samples;

viscera;

swabs;

hair;

toxicology samples;

weapons or instruments alleged to have caused injury.

The documentation should establish:

collection → packaging → sealing → labelling → custody → transportation → forensic laboratory receipt → examination → report.

This protects the evidentiary value of forensic material and reduces allegations of substitution or contamination.

14. NHRC reporting requirements

The NHRC has long required prompt reporting of custodial deaths.

Its published guidance records the requirement that information concerning custodial deaths be communicated to the Commission within 24 hours, with subsequent reports including the post-mortem and Magisterial Inquiry material.

The NHRC subsequently directed that the relevant reports, including:

post-mortem report;

videography material; and

Magisterial Inquiry report,

be supplied within the prescribed reporting period. The NHRC also clarified that authorities should not wait for the viscera report before sending the other available documents; the viscera report can follow when received.

Therefore, documentation should be treated as a continuing process rather than a single report prepared after death.

15. D.K. Basu v. State of West Bengal

Citation: D.K. Basu v. State of West Bengal, AIR 1997 SC 610.

Principle

The Supreme Court treated custodial violence as a serious violation of constitutional rights and established procedural safeguards concerning arrest and detention.

Relevance to documentation

The judgment is particularly important because it creates a documentary trail beginning at the moment of arrest.

Important records include:

arrest memo;

identity of arresting officers;

diary entries;

information to relatives;

injury inspection memo;

medical examination;

Magistrate records; and

custody-related communications.

Thus, documentation begins before the death occurs.

16. Nilabati Behera v. State of Orissa

Citation: Nilabati Behera v. State of Orissa, (1993) 2 SCC 746.

This is one of the leading Supreme Court decisions on custodial death.

The Court held that where violation of Article 21 is established, constitutional courts can award monetary compensation in public law proceedings under Articles 32 and 226.

The Court also made clear that such compensation is distinct from ordinary civil damages and criminal prosecution.

Significance

The case establishes three important propositions:

custodial death can constitute a violation of Article 21;

the State can be held liable in public law; and

compensation can be awarded independently of criminal or civil remedies.

The case therefore demonstrates why accurate documentation is crucial: a constitutional court may rely on documentary, medical and investigative material when determining whether State responsibility is established.

17. Paramvir Singh Saini v. Baljit Singh

Citation: (2021) 1 SCC 184.

This case transformed CCTV from merely desirable technology into an important accountability mechanism in police stations.

The Court required:

CCTV installation;

audio-video recording;

coverage of relevant police-station areas;

maintenance;

oversight committees; and

mechanisms for reviewing footage where human-rights violations are alleged.

Documentation significance

In a custodial death investigation, investigators should immediately identify and preserve relevant CCTV footage rather than allowing the normal retention period to expire.

18. Shafhi Mohammad v. State of Himachal Pradesh

The Supreme Court also recognised the importance of videography in investigation, particularly crime-scene documentation.

The principle is important in custodial death cases because the physical scene may subsequently change.

Relevant scenes may include:

lock-up;

interrogation room;

police vehicle;

alleged place of injury;

hospital;

location where the person allegedly collapsed.

The Court's CCTV jurisprudence subsequently incorporated the broader objective of using technology to improve transparency and accountability.

19. Distinguishing police inquest from Magistrate inquiry

This distinction is essential.

Under Section 196(2) BNSS, the Magistrate's inquiry is in addition to the police inquiry/investigation in a custodial death.

20. Documentation checklist

A comprehensive custodial-death file should, subject to the facts of the case, contain:

A. Arrest and custody

Arrest memo

Arrest register entry

General diary/station diary

Custody register

Names of responsible officers

Information sent to family

Remand papers

Magistrate records

B. Medical

Initial medical examination

Injury/inspection memo

Periodic medical examinations

Medical prescriptions

Hospital records

Emergency records

Referral documents

Death certificate

Medical cause-of-death opinion

C. Forensic

Inquest report

Post-mortem report

Post-mortem photographs

Post-mortem videography

Histopathology report

Toxicology/viscera report

DNA/biological evidence where relevant

FSL reports

D. Digital

CCTV footage

CCTV preservation certificate/record

DVR/NVR data

Access logs

Police vehicle GPS

Relevant call records

Wireless communication records

Hospital CCTV

E. Witnesses

Police personnel

Co-detainees

Medical personnel

Family members

Independent witnesses

Persons who saw the deceased immediately before or after custody

F. Administrative

NHRC intimation

Magisterial inquiry report

Senior-police-officer reports

Suspension/departmental proceedings where applicable

Compensation orders, if any

Final investigation report/charge-sheet

21. Evidentiary importance of discrepancies

In a custodial-death investigation, seemingly small discrepancies can become important.

Examples:

Arrest memo: 8:00 PM
CCTV: detainee enters at 5:30 PM

or:

Police record: no injury
Hospital record: multiple fresh injuries

or:

Police version: detainee became unconscious at 10:00 PM
CCTV: medical emergency appears significantly earlier

Such inconsistencies should be independently investigated rather than automatically resolved in favour of either side.

22. Responsibility for preservation

Once a custodial death occurs, authorities should act promptly to preserve evidence.

Particular attention should be given to evidence capable of automatic deletion or overwriting, such as:

CCTV;

server logs;

call records;

electronic access logs; and

digital communications.

The Supreme Court's CCTV jurisprudence places responsibility on police authorities for ensuring functioning, maintenance and recording. Paramvir Singh Saini specifically assigned responsibilities concerning CCTV operation and maintenance to police-station leadership and oversight mechanisms.

23. Constitutional remedy and compensation

Where custodial death amounts to a proven violation of Article 21, the victim's family may potentially seek public-law compensation through constitutional jurisdiction.

The principle established in Nilabati Behera is that compensation under Articles 32/226 can operate as a public-law remedy and does not necessarily replace:

criminal prosecution;

departmental proceedings; or

private-law damages.

The Supreme Court has continued to rely on Nilabati Behera in later cases concerning custodial violations.

24. Overall documentation standard

A good custodial-death investigation should be capable of answering five questions:

1. Who had custody?

Identify every officer/person who exercised physical or legal control over the deceased.

2. What was the person's condition when custody began?

This requires arrest documentation and medical examination.

3. What happened during custody?

This requires CCTV, station diaries, witness evidence, medical records and other electronic evidence.

4. What caused the death?

This requires independent forensic and medical investigation.

5. Was the State's version independently verifiable?

This requires preservation of original documentary, electronic and forensic evidence.

25. Conclusion

Documentation of a death in police custody must be contemporaneous, comprehensive, independent, medically supported and digitally preserved.

The present legal framework is built around:

Article 21 Constitution → D.K. Basu safeguards → Sections 194 and 196 BNSS → NHRC custodial-death guidelines → post-mortem and videography → CCTV/electronic evidence → independent Magistrate inquiry → judicial review and compensation where constitutional rights are violated.

The most important authorities are:

Nilabati Behera v. State of Orissa, (1993) 2 SCC 746 — constitutional compensation for custodial death and Article 21 violation.

D.K. Basu v. State of West Bengal, AIR 1997 SC 610 — mandatory safeguards concerning arrest, detention, medical examination and documentation.

Shafhi Mohammad v. State of Himachal Pradesh — importance of videography in investigation.

Paramvir Singh Saini v. Baljit Singh, (2021) 1 SCC 184 — CCTV, audio-video recording and oversight in police stations.

Section 196 BNSS, 2023 — mandatory Magistrate inquiry into a death or disappearance in police custody, in addition to police investigation.

NHRC custodial-death guidelines — prompt intimation, post-mortem documentation, videography and Magisterial Inquiry reporting.

Core principle: In a custodial-death case, documentation is itself a safeguard of Article 21. The purpose is not simply to record that a person died, but to create a reliable evidentiary record showing how, when, where and under whose custody the person died, while preserving sufficient independent material for a fair determination of responsibility.

This is an academic legal overview. In an actual custodial-death matter, the applicable State rules, current NHRC directions, forensic protocols and facts of the individual case should also be examined.
