The Central Bureau of Investigation (CBI) has commenced lie detection tests on the primary suspect and six others linked to the rape and murder of a trainee doctor at RG Kar Medical College and Hospital in Kolkata. The main suspect, Sanjay Roy, will undergo a polygraph test at the prison where he is held. The other six individuals—including former principal Sandip Ghosh, four doctors on duty the night of the incident, and a civil volunteer—will be tested at the CBI office.
A specialized team from the Central Forensic Science Laboratory (CFSL) in Delhi has been sent to Kolkata to conduct these tests. The CBI has informed the Supreme Court of attempts to tamper with evidence at the crime scene before the agency took over the investigation.
The assault occurred on the night of August 8-9. CBI sources reveal that the victim had dinner with two first-year postgraduate trainees around midnight. Afterward, they moved to a seminar room to watch Neeraj Chopra’s javelin event at the Tokyo Olympics. At around 2:00 a.m., the trainees left, but the victim stayed behind. An intern, also present on the third floor that night, claimed to have remained in the interns’ room nearby.
The next morning, at approximately 9:30 a.m., one of the trainees who had dined with the victim went to check on her before ward rounds and found her body. The trainee alerted his colleagues and senior doctors, who then informed the hospital authorities.
The investigation has uncovered significant evidence. Fingerprints of two of the four doctors were found in the seminar room where the victim’s body was discovered. Additionally, CCTV footage from the hospital shows Sanjay Roy entering the college at 1:03 a.m. on the night of the crime, wearing a Bluetooth earphone around his neck. A similar Bluetooth device was found at the crime scene during the initial investigation.
The case has triggered widespread protests across India, with intense demonstrations in Kolkata. In response, the Supreme Court has ordered the deployment of Central Industrial Security Force (CISF) personnel to enhance security around the hospital.
