The main suspect in the Kolkata rape and murder case, Sanjay Roy, has denied any involvement in the gruesome incident during a polygraph test conducted by the Central Bureau of Investigation (CBI). News broadcaster India Today reported citing sources that Roy fled the crime scene as soon as he discovered the dead body at the RG Kar Medical College and Hospital.
As per the report, CBI asked Roy ten questions during the polygraph test. An investigating officer from the CBI and three polygraph test experts were present during the examination, reportedly conducted on August 25 at Kolkata's Presidency Central Jail.

Roy had initially confessed to the crime on August 10 following his arrest but the civic volunteer later took a U-turn and claimed he was being framed.
Sanjay Roy is believed to have told the CBI that he was not involved in the incident.
"I didn't commit the murder. I ran from the seminar hall after seeing the body," he told CBI during the test.
It must be noted that the results of the polygraph tests are not admissible as evidence in the courts.
Sanjay Roy's lawyer Kavita Sarkar said Roywas asked during the test what did he after murdering the junior doctor. Roy then reportedly told the CBI that the question was invalid as he didn’t commit the murder.

"CBI couldn't produce conclusive evidence so far. Let them investigate and prove the crime," the lawyer was quoted as saying by India Today.
As per reports, the test also flagged several false and unconvincing answers.
Earlier, the CBI said it had conducted nearly 10 polygraph tests and recorded over 100 statements in connection with the case. The agency has evidence that only implicates Sanjay Roy, as per media reports.
The agency had already ruled out the possibility of gang rape in the murder case, identifying Roy as the only suspect.
