RG Kar PG Medico death case: CBI finds Sandip Ghosh's responses 'deceptive' in polygraph test

Kolkata: The Central Bureau of Investigation (CBI) has accused RG Kar Medical College’s former principal Sandip Ghosh of delaying the registration of an FIR in connection with the rape and murder of a postgraduate doctor trainee. The officials also reported that Ghosh gave "deceptive" answers to important questions during a polygraph test.

RG Kar Medical College’s former principal Sandip Ghosh was found to be ''deceptive'' while answering important questions on the rape and murder of a trainee woman postgraduate doctor during his polygraph test and layered voice analysis, officials said.

Ghosh was arrested by the CBI on September 2 for alleged financial irregularities at the hospital, and additional charges of evidence tampering have since been brought against him.

According to the PTI report, during the investigation, Ghosh was subjected to layered voice analysis and polygraph test.

According to a report from Central Forensic Science Laboratory (CFSL), New Delhi, his version has been found to be “deceptive on certain important issues” relating to this case, officials in the know of the developments said.

Information revealed during the polygraph test may not be used as evidence during the trial but the agency may gather corroborative evidence which could be used in court, they said.

A polygraph test can help in assessing inaccuracies in the statements of suspects and witnesses. By monitoring their psychological responses, heart rate, breathing pattern, sweating and blood pressure, investigators can determine if there are discrepancies in their responses.

The CBI has alleged that Ghosh got information about the rape and murder of the trainee doctor at 9.58 am on August 9 but he did not make the police complaint immediately.

He allegedly made a “vague complaint” at a later stage through the medical superintendent-vice principal even though the victim was declared dead at 12.44 pm, they said, news agency PTI reported.

“He did not try to get an FIR lodged immediately. Rather a new theory of suicide was introduced which is not possible as per external injury visible on the body of the victim that was undressed at the lower part,” the CBI has alleged, adds PTI.

The probe agency has alleged that Ghosh got in touch with Tala Police Station’s Officer In Charge (OC) Abhijit Mondal at 10.03 am and with an advocate at 1.40 PM while a case of unnatural death was registered at 11.30 pm.

Mondal, who has also been arrested by CBI in connection with the case, received information of the incident at 10.03 am on August 9 but did not reach the scene of the crime immediately, the officials claimed, adding the OC reached the spot after an hour.

The general diary entry 542 mentioned that the body of the PG trainee of RG Kar Medical College and Hospital was found lying in an “unconscious state” in the seminar room of chest medicine, whereas the body was already examined by a doctor who had found the victim dead.

The general diary entry was allegedly made “in conspiracy with hospital authorities and other unknown persons”, intentionally mentioning wrong details.

Mondal’s failure to register an FIR and protect the scene of crime resulted in the “damage of vital evidence available at the crime scene”, officials said, adding he tried to protect the accused Sanjay Roy and others who had unauthorised access to the scene of crime that might have led to tampering of evidence.

Ghosh allegedly directed subordinates to send the body to the morgue hurriedly, they said.

The trainee doctor was allegedly raped and murdered in the seminar hall of R G Kar Medical College and Hospital when she had gone to rest during her shift in the early hours of August 9. Her body with severe injury marks was found in the hall by a doctor who was on rounds.

Sanjay Roy, a police volunteer, was arrested the next day based on CCTV footage in which he was seen entering the seminar hall at 4.03 am on the day of the incident.

On August 13, the Calcutta High Court ordered the case to be transferred from the Kolkata Police to the CBI, which officially took over the investigation on August 14.
