The rape and murder of a 31-year-old postgraduate trainee doctor at R.G. Kar Medical College and Hospital, Kolkata, on 9 August 2024, became one of the most significant criminal cases in India's recent legal history. It tested the new criminal codes (BNS/BNSS), the limits of State Police investigation, the Calcutta High Court's transfer powers, and the Supreme Court's suo motu jurisdiction. This legal analysis by FileX Advocates & Legal Consultants, Kolkata examines the procedural framework, the investigation, the trial, and the wider impact on medical safety law in West Bengal.
1. The Crime and the First 72 Hours
The victim, a second-year postgraduate trainee in chest medicine, was found dead in a seminar hall of the RG Kar Medical College on the morning of 9 August 2024 after a 36-hour shift. The autopsy confirmed rape and strangulation. The Kolkata Police registered an FIR and arrested Sanjay Roy, a 33-year-old civic volunteer attached to the Kolkata Police disaster management force posted at the RG Kar police outpost, on 10 August 2024.
Several procedural issues emerged early:
- Alleged delay in registering the FIR and informing the family.
- Alleged haste in declaring the death and moving the body before proper inquest.
- Renovation work at the crime scene reportedly begun while the investigation was ongoing, raising concerns of destruction of evidence.
2. Calcutta High Court Transfers the Investigation to CBI (13 August 2024)
On 13 August 2024, a Division Bench of the Calcutta High Court transferred the investigation from the Kolkata Police to the Central Bureau of Investigation (CBI), exercising its inherent powers under Section 407 CrPC (now Section 408 BNSS would apply to fresh transfers). The Court cited a loss of public confidence in the State Police, the destruction of evidence concerns, and the need for an impartial federal agency. The CBI constituted a 25-member team and re-registered the FIR.
This transfer is legally significant because:
- It invoked the High Court's power to transfer investigation (not just trial) — a power the Supreme Court has recognised in exceptional cases of compromised State machinery.
- It bypassed the usual requirement of a State government recommendation for CBI investigation.
- The Court directed the CBI to file periodic status reports under sealed cover.
3. Supreme Court Takes Suo Motu Cognizance (August 2024)
The Supreme Court of India took suo motu cognizance of the incident on 18 August 2024, titled In Re: Alleged Rape and Murder Incident of a Trainee Doctor in R.G. Kar Medical College and Hospital, Kolkata & Other Connected Matters. A three-judge Bench led by the then Chief Justice D.Y. Chandrachud:
- Constituted a National Task Force (NTF) to recommend measures for the safety of medical professionals, particularly women, across India.
- Directed the CBI to file a status report on the investigation.
- Ordered the West Bengal government to ensure safe conditions for protesting doctors returning to work.
- Permitted the trial to proceed on a day-to-day basis with the help of the new BNSS provisions.
The suo motu invocation of Article 32 underscored that the safety of medical professionals is a matter of fundamental rights and public interest, beyond the individual case.
4. BNS Sections Applied: 64, 66, and 103(1)
The CBI chargesheet and the trial court framed charges under the Bharatiya Nyaya Sanhita, 2023 (BNS), since the offence occurred after 1 July 2024:
- Section 64 BNS — rape (replacing Section 375/376 IPC). Defines the offence and prescribes minimum sentences.
- Section 66 BNS — rape causing death or resulting in a persistent vegetative state (replacing Section 376A IPC).
- Section 103(1) BNS — murder (replacing Section 302 IPC), punishable with death or life imprisonment.
The procedural framework was governed by the BNSS 2023, including mandatory forensic investigation under Section 176 BNSS (since the offences carry 7+ years), the two-month investigation limit for sexual offences (Section 193(2)), and the two-month trial limit for listed sexual offences (Section 346 proviso).
5. The Trial: Speed and Forensic Evidence
The trial began before the Additional District and Sessions Judge, Sealdah (Kolkata), Judge Anirban Das, on 11-12 November 2024 and concluded in an in-camera trial of about 57 to 66 days — among the fastest in a capital case in recent times, reflecting the BNSS day-to-day trial mandate. Key evidence:
- DNA matches from hair and skin samples recovered from the victim and the accused.
- CCTV footage placing Roy in the seminar hall corridor around the time of the crime.
- Bluetooth headset of the victim found in Roy's possession.
- Multi-institutional medical board report concluding the cause of death as manual strangulation and smothering.
- Roy's contradictory statements claiming he was "framed."
The defence argued that the seminar hall was near a 24/7 nursing station, making the crime improbable without notice. The court rejected this, accepting the forensic and circumstantial evidence.
6. The Conviction and Sentencing (January 2025)
On 18 January 2025, the Sealdah court convicted Sanjay Roy under BNS Sections 64, 66, and 103(1). On 20 January 2025, he was sentenced to life imprisonment for the remainder of natural life, with a fine of Rs 50,000. The court declined to impose the death penalty, holding that the case did not meet the "rarest of rare" standard from Bachan Singh v. State of Punjab (1980), and that the prosecution had not shown Roy was beyond reform.
The court directed the West Bengal government to pay Rs 17 lakh compensation to the victim's family, recognising that the crime occurred at the victim's workplace — a vicarious acknowledgement of institutional responsibility. The victim's family expressed disagreement with the sentence and pursued further legal remedies.
7. Destruction of Evidence Charges Against Former Principal and Police Officer
The CBI separately arrested Sandip Ghosh, former Principal of RG Kar Medical College, and Abhijit Mondal, the Station House Officer of Tala Police Station, for alleged destruction of evidence and misleading the investigation (corresponding to BNS Section 238 / 239 read with Section 201 IPC equivalent). They were later released on bail pending trial. This strand of the case highlights how institutional actors can face independent criminal liability for tampering with a crime scene.
8. Impact on Medical Safety and Workplace Law in West Bengal
- The National Task Force submitted recommendations on hospital security, duty hours, CCTV coverage, panic buttons, and safe rest areas for women medical professionals.
- West Bengal enacted "Aparajita Woman and Child Bill (West Bengal)"-style measures to enhance penalties for offences against women, mirroring national demand for stricter laws.
- Hospitals across Kolkata (RG Kar, SSKM, NRS, Calcutta Medical College) reviewed night-duty protocols, security deployment, and access to seminar halls and rest rooms.
- The case accelerated discussion on the implementation of the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013 (POSH Act) in government hospitals, which were often without functioning Internal Complaints Committees.
9. Procedural Lessons for Future Cases
- The BNSS mandate of forensic investigation for 7+ year offences (Section 176) proved decisive — DNA and CCTV made the case where eyewitnesses were absent.
- The two-month investigation and trial deadlines for sexual offences (Sections 193(2) and 346) showed that fast-track justice is achievable under the new code.
- Calcutta High Court's readiness to transfer investigation to the CBI sets a precedent for cases where State machinery is suspect.
- The Supreme Court's suo motu intervention demonstrates that fundamental rights at the workplace can be enforced even without a formal petition.
Frequently Asked Questions
Under which law was Sanjay Roy convicted — IPC or BNS?
He was convicted under the Bharatiya Nyaya Sanhita, 2023 — Sections 64 (rape), 66 (rape causing death), and 103(1) (murder). Because the offence occurred on 9 August 2024, after the BNS came into force on 1 July 2024, the BNS applied, not the IPC.
Why was the death penalty not imposed?
The trial court held that the case did not satisfy the "rarest of rare" threshold from Bachan Singh v. State of Punjab (1980) and that the prosecution had not established the accused was beyond the possibility of reform — a prerequisite for capital sentencing. Life imprisonment for natural life was imposed instead.
Why did the Calcutta High Court transfer the case to the CBI?
The Court cited loss of public confidence in the Kolkata Police, concerns about destruction of evidence (renovation at the crime scene), and the need for an impartial investigation. It exercised inherent powers to transfer the investigation to a central agency.
What did the Supreme Court's National Task Force do?
The NTF was constituted to recommend nationwide measures for the safety of medical professionals — including hospital security, duty-hour limits, CCTV, and safe rest areas — and its recommendations have shaped hospital safety policy in West Bengal and beyond.
What is the current legal status of the other accused (former principal, police officer)?
They face charges for destruction of evidence and misleading the investigation, separately tried from the main conviction. They were granted bail pending trial, and proceedings continue before the relevant court in West Bengal.
