The psychoanalytic profile of Sanjay Roy, the prime accused in the Kolkata rape-murder case, indicated that he was addicted to pornography, had "animal-like instincts" and showed no remorse for the crime, an officer of the Central Bureau of Investigation (CBI) said on Thursday.

The CBI on August 18 had ordered experts from CFSL to carry out a psychoanalytic profile of Roy. A civic volunteer with Kolkata Police, Roy was arrested the day after the body of the 31-year-old trainee doctor was found at the state-run RG Kar Medical College and Hospital on August 9.

The man showed no repentance and narrated the entire episode giving every minute detail without hiccups. It appeared that he had no remorse," the CBI official told news agency PTI on Thursday.

Before the investigation was handed over to the CBI by the Calcutta High Court, the local police had found a trove of pornographic content on the mobile phone seized from Roy.

The CBI officer also highlighted that both technical and scientific evidence "very much support" that Roy was present at the crime scene.

Based on the CCTV footage collected from the hospital, Roy could be seen near the chest department ward at around 11 am on August 8.

Sources had revealed earlier to India Today that Roy also visited a 'red light area' in North Kolkata after midnight on August 8. He was also intoxicated and later asked a random woman for her nude photograph.

"Footage showed him entering the same building again at around 4 am on August 9. Certain technical and scientific evidence corroborated that," the officer added.

In his interview with PTI, the officer refused to divulge any information about the DNA tests conducted on Roy or comment on the gang rape rumours.

Roy's residence in Bhowanipore was also visited by CBI officers where they spoke with his family, neighbours and his colleagues in the Kolkata Police force.
