Sanjay Roy, the lone accused chargesheeted for the RG Kar rape and murder, was brought to the Sealdah court on Tuesday for identification by witnesses, including a civic volunteer who prosecutors said accompanied him to the hospital on the night of the crime.

The four witnesses who deposed before the court on Tuesday included two civic volunteers and two policemen. According to the CBI findings, all four had seen or met Roy on the night of the crime.

A junior doctor was raped and murdered in a seminar hall on the third floor of the Emergency building at RG Kar Medical College and Hospital early on August 9.

The process of identification was meant to corroborate the investigation and the evidence submitted by the central agency.

Following a court directive, based on a plea by the prosecution, Roy is no longer brought to the court toattend the trial. Instead, heis allowed to follow theproceedings through video conferencing.

When he was brought to the court on the first few days of the trial, Roy shoutedthe names of police officers who he alleged had framed him. That prompted theauthorities to increase the number of vehicles in Roy’s convoy so reporters and others could not reach the one transporting the accused.

An exception was made on Tuesday for physical identification of the accused by witnesses, which is an essential part of any trial.

One of the civic volunteers who deposed on Tuesday had accompanied Roy to the hospital on the night of August 8, sources in the CBI said. The other civic volunteer had spent some time with Roy on the evening of August 8.

One of the cops who deposed was present in thebarracks of the fourth battalion of Kolkata Police, from where Roy was brought to Tala police station on the night of August 9.

The other cop was posted at the RG Kar police outpost on August 8, CBI officers said.

Former RG Kar principal Sandip Ghosh, on whose watch the 31-year-old doctor was raped and murdered, and former Tala police station officer-in-charge Abhijit Mandal were arrested in the case on charges of evidence tampering. Neither has been chargesheeted yet.

Usually, it takes several months, if not years, for a trial to start. But this case has been fast-tracked and the trial started within three months of the crime.

The trial began on November 11. Till Tuesday, 31 witnesses have deposed.

Lawyers said that if needed, Roy would be brought to the court again for a second round of identification by witnesses.
