CBI questions close aide of arrested ex-principal of RG Kar Medical College         

In connection with the probe into the rape and murder of a woman doctor, CBI sleuths started questioning another doctor — allegedly close to arrested former principal of RG Kar Medical College and Hospital Sandip Ghosh — on Saturday, an officer of the agency said.

Birupaksha Biswas, who was recently transferred by the West Bengal Health Department from Burdwan Medical College and Hospital to remote Kakdwip hospital in South 24 Parganas district, appeared before officers of the Central Bureau of Investigation at its CGO Complex office in Salt Lake area.

Biswas, allegedly part of a 'North Bengal lobby' operational in medical colleges, was seen at RG Kar Hospital on August 9, when the body of the woman medic was found, the CBI officer said.

The 'North Bengal lobby' is being referred to a group of doctors and officials posted at state-run medical establishments by medics in West Bengal who allegedly threatened students.

"He is being questioned about his presence at RG Kar Hospital on August 9 despite having no official engagement, apart from other queries," the officer told PTI.

An FIR has been lodged against Biswas and two other doctors — Avik De and Ranjit Saha — with Bowbazar police station for allegedly threatening students at different medical colleges and hospitals across West Bengal. They have been booked under Section 351 of the Bharatiya Nyay Sanhita.
