New Delhi: A special court in Kolkata on Friday allowed a polygraph test to be conducted on Sanjay Roy, the main accused in the rape and killing of a trainee doctor at the state-run RG Kar Medical College and Hospital, officials said.
The court has already given its nod to conduct the lie-detection test on Sandip Ghosh, the former principal of the medical college, and four other doctors who were on duty at the hospital in the intervening night of August 8-9, they said.
CCTV footage and a bluetooth device found near the medic's body resulted in the arrest of Roy, who was seen entering the seminar hall of the college where the body was found.
Roy (33) joined the Kolkata Police as a civic volunteer in 2019. Police have alleged that he was married at least four times and was a known "womaniser".
The accused, who is a trained boxer, got close to a few senior police officers over the years, following which he was moved to the Kolkata Police Welfare Board and posted at the police outpost at the RG Kar Medical College and Hospital.
A team of experts from the Central Forensic Science Laboratory (CFSL) in Delhi will conduct the tests, the officials said.
The Central Bureau of Investigation (CBI) is also awaiting Roy's DNA and psychoanalysis reports, which will give further direction to its investigation, they said.
The CBI told the Supreme Court on Thursday that there was an attempt to cover up the rape and killing of the post-graduate medic by the local police as the crime scene was altered by the time the federal agency took over the probe.
The rape and killing of the junior doctor in a seminar hall of the hospital has sparked widespread protests.
The medic's body with severe injury marks was found inside the seminar hall of the hospital's chest department in the morning of August 9. Roy was arrested the following day.
On August 13, the Calcutta High Court ordered the transfer of the probe from the Kolkata Police to the CBI, which started its investigation on August 14.
