The Central Bureau of Investigation (CBI) is set to conduct a polygraph test on Friday on Dr Sandip Ghosh, the former Principal of RG Kar Medical College and Hospital, in connection with the brutal rape and murder of a 31-year-old trainee doctor at the state-run facility on August 9.
The decision, reported by the NDTV, comes after CBI officials reportedly failed to obtain satisfactory responses from Ghosh during more than 88 hours of questioning over the past week.
While polygraph test results are not admissible in court, they are often used by investigators to gather clues and lead the investigation in the right direction. The CBI is hoping this test might provide further insight into the case, which has captured national attention.
Dr. Ghosh’s actions following the discovery of the doctor’s body in a seminar hall have been under intense scrutiny, both in the Calcutta High Court and the Supreme Court. Both courts have repeatedly questioned his role, raising concerns over possible misconduct.

Dr. Sandip Ghosh is also under investigation by the state government for corruption and is involved in a separate case concerning the alleged disclosure of the victim’s identity.
In addition to Dr. Sandip Ghosh, four other doctors who were on duty the night of the incident will also undergo polygraph tests. The CBI received approval for these tests from a special court Thursday.

The main accused in the case, Sanjay Roy, a civic volunteer with the Kolkata Police, is also under investigation by the CBI. The agency has requested a polygraph test for Sanjoy Roy as well, with the Supreme Court directing a Kolkata court to decide on this request by the end of the day.
Sanjoy Roy was arrested on August 10, a day after the doctor’s half-naked body was discovered in the hospital’s seminar hall. His 14-day police custody is scheduled to end Friday, and he will be produced in the Sealdah court.
The case continues to evolve, with the polygraph tests potentially playing a critical role in determining the course of the investigation.
