Days after Sanjay Roy claimed innocence in the case, he was subjected to the lie-detection test by the CBI during which he said the woman doctor was already dead when he reached the seminar hall, where her body was found on August 9
The polygraph test conducted on Sanjay Roy, the main accused in the alleged rape-murder of a trainee doctor in Kolkata’s RG Kar Medical College and Hospital, reportedly flagged several false and unconvincing answers.
Days after Roy claimed innocence in the case, he was subjected to the lie-detection test by the CBI on Sunday (August 25). During the test, he said the woman doctor was already dead when he reached the seminar hall of the RG Kar hospital where the body was found on August 9.
According to a report published by the Times of Indiasources said he appeared to be nervous and anxious when he took the polygraph. He was confronted with multiple evidence to which he cited alibis and told the investigation team that the victim was already dead when he spotted her, following which he ran from the premises in fear, the report said.
The report said Roy’s lawyer Kavita Sarkar alleged that the defence counsel was not informed about the time and venue of the polygraph test. As a result of this, a defence lawyer was unable to be present during the test, which is in violation of guidelines by the National Human Rights Commission.
A civic volunteer of the Kolkata Police, 33-year-old Roy was arrested by the Kolkata Police on August 10, a day after the body of the 31-year-old doctor was found in the seminar hall of the medical college. However, after initially confessing to the crime and even providing help in reconstructing the incident, he made a U-turn and claimed innocence saying he is being framed.
An officer said the lie-detection test was conducted at Kolkata’s Presidency Jail where the main accused is currently lodged. The CBI also conducted polygraph tests on a couple of others at the Kolkata office, adding that the test on Roy was over after around four hours.
A team of polygraph specialists were flown to Kolkata from the Central Forensic Science Laboratory (CFSL) in Delhi. Four persons, including former principal Sandip Ghosh, underwent the polygraph test on August 24.
The CBI has sought permission from a local court in Kolkata to put seven persons, including Roy and Ghosh, through the lie-detector test that cannot be used as evidence during the trial. The findings, however, give the agency a direction to further the probe.
