The CBI on Monday arrested Sandip Ghosh, the former principal of Kolkata’s RG Kar Medical College and Hospital where a junior doctor was raped and murdered last month.

The arrest followed Ghosh’s questioning by the central agency for the 15th day. He was later escorted to the CBI's Nizam Palace office in Kolkata which houses the agency's anti-corruption wing.

The CBI had earlier carried out an extensive search of Ghosh’s house in Kolkata and monitored his call details. The the initial probe had reportedly hinted that Ghosh made a long phone call to "someone influential" on the day the woman doctor was found dead.

The trainee doctor was found murdered at the seminar hall of the hospital after being raped on August 9, sparking nationa-wide outrage.

Ghosh resigned from his post days after the incident, taking moral responsibility, but within hours the West Bengal government appointed him as the principal of Calcutta National Medical College and Hospital. The government’s move sparked a fresh wave of protests, prompting the Calcutta High Court to intervene and send him on “long leave”.

The hospital's former deputy superintendent Dr Akhtar Ali had lodged complaints of financial irregularities on multiple counts at the establishment during Ghosh's tenure as principal.
