RG Kar case: Family moves Sealdah court over viscera tampering allegations
Synopsis
The RG Kar case has taken a grave new turn: the victim's family has moved a Sealdah court after receiving a letter — twice — alleging that viscera samples were swapped at the Belgachia forensic lab on orders linked to the then Chief Minister or TMC. The CBI, informed in May, reportedly took no action for over six weeks, forcing the family to seek judicial intervention.
Key Takeaways
The RG Kar victim's family moved Sealdah court on 2 July 2025 over a letter alleging viscera sample tampering.
The letter, purportedly from a former Belgachia Forensic Science Laboratory employee, names three officials allegedly involved in swapping samples.
Tampering was allegedly ordered by the then Chief Minister or TMC ; the same officials allegedly swapped samples linked to BJP and CPI-M workers.
The family received the letter on 16 May and again on 23 May ; the CBI was informed but reportedly took no action.
The victim's body was found at RG Kar Medical College and Hospital on 9 August 2024 ; civic volunteer Sanjay Roy was arrested the following day.
The family of the victim in the RG Kar rape and murder case has approached a Sealdah court in Kolkata, after receiving a letter alleging that their daughter's viscera samples were tampered with at the State Forensic Science Laboratory in Belgachia. The family appeared before the court on Thursday, 2 July 2025, seeking judicial verification of the claims and an independent investigation.
What the Letter Alleges
The letter, reportedly authored by a self-described former employee of the Belgachia Forensic Science Laboratory, claims that viscera samples collected for forensic analysis were tampered with before being dispatched to the Central Bureau of Investigation (CBI) and the Central Forensic Science Laboratory. The sender allegedly named three officials of the Belgachia laboratory as being involved in the swapping of samples — though their identities have not been made public by the media.
The letter further alleged that the tampering was carried out on the orders of the then Chief Minister or the All India Trinamool Congress (TMC). It also claimed that, during the Trinamool era, the same officials had swapped hundreds of viscera samples linked to Bharatiya Janata Party (BJP) or Communist Party of India (Marxist) (CPI-M) workers, and that substandard materials had been used in forensic tests.
The Family's Account
According to the victim's father, the family received the letter twice — first on 16 May and again on 23 May. He stated that the CBI was informed after the first letter arrived but took no action, prompting the family to escalate the matter to the court.
The victim's father said: 'We received a letter in May. We immediately informed the CBI. But they did not take any action. Seven days later, the same letter came again. It says that the viscera report has been distorted. Who did it, on whose orders it was done, everything is written. I have informed the CBI. Now we have come to the court. Surely the CBI will take necessary action.'
The family requested the court to verify the letter's authenticity and direct a formal probe into the allegations. The identity of the sender has not been disclosed by the family, according to officials aware of the matter.
A Question Over State Officials
The victim's father also publicly questioned why state Health Secretary Narayan Swarup Nigam continues to hold his post even after the change of government in West Bengal — a pointed query that connects the forensic tampering allegations to broader concerns about administrative continuity and accountability.
Background: The RG Kar Case
The body of the female doctor was recovered at RG Kar Medical College and Hospital on 9 August 2024. The following day, civic volunteer Sanjay Roy was arrested by the Kolkata Police in connection with the case. The Calcutta High Court subsequently ordered the CBI to take over the investigation. The case has remained a flashpoint for public outrage and political controversy in West Bengal ever since.
This latest development — allegations of forensic evidence tampering — introduces a new and serious dimension to an already deeply contested case, with the family now seeking court intervention after the CBI reportedly failed to act on their complaint for over six weeks.
Point of View
They strike at the integrity of the entire forensic chain in one of India's most politically charged criminal cases. The more troubling detail, however, is procedural: the family says they informed the CBI in May and were met with silence for over six weeks. An investigating agency that does not respond to an allegation of evidence tampering in its own case raises serious questions about the robustness of the probe. The continued presence of Health Secretary Narayan Swarup Nigam — flagged by the victim's father — adds a layer of administrative accountability that neither the CBI nor the new state government appears to have addressed publicly. Courts may now have to do the work that investigative agencies have not.
