A team of the federal agency also questioned Roy, who is now lodged in the Presidency correctional home, on Wednesday.

“His swab and dental impression were collected by the federal agency in the jail,” said a person aware of the development.

A sample of dental impression was used as evidence for the first time in the Delhi gang-rape case of December 16, 2012.

Meanwhile, a team of CBI officials on Thursday questioned Sudipto Roy, Trinamool Congress (TMC) legislator from Sreerampore.

Sudipto is also the chairman of the RG Kar Hospitals patient’s welfare committee.

The case came to light on August 9, when the body of the woman postgraduate trainee doctor was found in a seminar hall at RG Kar Medical College and Hospital (RGKMCH). The following day, the main accused Sanjay Roy was arrested.
