Kolkata Doctor Death: Kolkata Court Allows Polygraph Test Of Accused Sanjay Roy


A special court in Kolkata has now approved a polygraph test for Roy, the primary suspect in the rape and murder of a trainee doctor at RG Kar Medical College and Hospital.


In addition to Roy, the court has also sanctioned lie-detection tests for Sandip Ghosh, the former principal of the medical college, and four doctors who were on duty on the night of August 8-9, news agency PTI reported.


Roy, aged 33, joined the Kolkata Police as a civic volunteer in 2019. Known for his background as a trained boxer and a history of multiple marriages, he had reportedly developed connections with senior police officers, which led to his assignment at the Kolkata Police Welfare Board and subsequent posting at the RG Kar Medical College and Hospital.


Experts from the Central Forensic Science Laboratory (CFSL) in Delhi will conduct the polygraph tests. The Central Bureau of Investigation (CBI) is also awaiting Roy's DNA and psychoanalysis reports to further advance its investigation. The CBI informed the Supreme Court on Thursday that there was an attempt to cover up the crime, with alterations to the crime scene before the federal agency took over the investigation.


The rape and murder of the junior doctor, discovered with severe injuries in the seminar hall of the hospital on August 9, has ignited widespread protests. Roy was arrested the day after the body was found. On August 13, the Calcutta High Court transferred the case from the Kolkata Police to the CBI, which began its investigation on August 14.
