Kolkata rape-murder case: Accused Sanjay Roy's polygraph test not done today due to technical issue

The Central Bureau of Investigation (CBI) conducted the polygraph test of six people, including Sandeep Ghosh, related to the Kolkata rape and murder case. The polygraph test on the main accused, Sanjay Roy, could not be done on Saturdat in the prison, where he is lodged, due to a technical issue, officials said. The remaining six, including former principal Sandip Ghosh and four doctors who were on duty during the night of the incident and a civil volunteer, underwent test at the agency's office, the officials said. A team of polygraph specialists from the Central Forensic Science Laboratory (CFSL) in Delhi have flown to Kolkata to conduct these tests, 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.

"Sanjay Roy's test in jail will take place tomorrow, and the polygraph tests for Sandeep Ghosh and others are currently ongoing. Today, due to some technical issues and arrangements with the jail administration, Sanjay Roy's polygraph test could not be conducted. The test for the main accused will happen tomorrow, while the others are ongoing," officials said.

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.
