Sanjay Roy, the lone suspect arrested so far in the rape and murder of a doctor in a Kolkata hospital, reportedly said in the polygraph test on August 25 that the victim was dead when he spotted her, and that he had run away in fear, according to a report by Times of India.
As per the report citing sources, Roy appeared "unnerved and anxious" during the questioning. The lie detector test on Roy flagged several "false and unconvincing answers", report added.
Central Bureau of Investigation (CBI) officers conducted the lie-detection test on the prime accused in the alleged rape and murder of a lady doctor at the RG Kar Medical College and Hospital in Kolkata. CCTV footage reportedly showed Roy entering the emergency building at 4am on the day of the incident, wearing a bluetooth device. When he left 40 minutes later, the device was missing. It was later found near the victim’s body. The police paired it with Roy's cellphone and thus linked him to the crime.
The lie-detection test was conducted at Kolkata's Presidency Jail where Roy is lodged, the report added.
A polygraph test popularly known as a lie detector test is conducted by using a machine that measures a person’s physiological responses when they respond to various questions. According to the American Psychological Association, the purpose of the test is usually to prove whether or not a person committed a crime. It, however, cannot test for honesty.
Roy reportedly turned emotional when the judge asked him why he was consenting to the polygraph test, according to another report by TOI.
The accused told the court that he did not do anything and is being framed. "I haven’t committed any crime. I’m being framed. Maybe this test will prove that,” he was quoted as saying by the publication.
