Calcutta doctor rape case: Sanjoy Roy pleads not guilty, calls CBI's lie detector questions on murder “invalid”

Kolkata doctor rape case: Arrested volunteer Sanjoy Roy is likely to plead 'not guilty' in court, a media report said, citing his lawyer Kavita Sarkar. Sanjoy Roy was arrested on August 10, a day after the trainee doctor's body was found in a seminar room of RG Kar Medical College and Hospital. Roy, who has undergone a polygraph test, also known as a lie detector test, reportedly termed the CBI investigator's question about the doctor's 'murder' as 'invalid'.

According to a report in the Times of India, Sanjoy Roy maintained his innocence throughout a lie detector test conducted by the CBI as part of the ongoing investigation into the rape and murder case of a Kolkata doctor.

Sanjoy Roy's lie detector test by CBI

According to media reports citing Sanjoy Roy's lawyers, the arrested volunteer was asked 10 questions by the CBI. The questions included a question on his academic background and some questions related to the doctor's Kolkata rape and murder case.

According to the ToI report, when Sanjoy Roy was asked what he did after “murdering” the PGT doctor of RG Kar Hospital, the volunteer interrupted the CBI sleuths and claimed that he “did not murder the doctor”.

Roy allegedly claimed that the doctor was covered in blood and unconscious when he entered the seminar hall. The arrested accused also claimed that he “panicked and ran out of the seminar hall” after seeing the doctor.

When Sanjoy Roy was asked why he did not inform the CBI or the Kolkata Police about these developments earlier, the arrested volunteer claimed that “nobody would believe him”. He added that he had been “deceived”.
