Kolkata: In a recent development, the Anti-Corruption Branch of the Central Bureau of Investigation (CBI) has arrested Dr Sandip Ghosh, the former principal of RG Kar Medical College, along with three others, in connection with alleged corruption and financial misconduct at the institution.

Dr Ghosh was being investigated for financial irregularities at RG Kar Medical College and Hospital following a directive from a Calcutta High Court bench that ordered the CBI to probe the matter.

According to an ANI report, in addition to Dr Ghosh, two vendors, Biplav Singha and Suman Hazara, as well as Afsar Ali, the Additional Security to Dr Ghosh, have been arrested, the sources added.

Ghosh was taken to the CBI's Anti-Corruption Branch from the CBI's Special Crime Branch office following an ongoing investigation into a corruption case registered against him.

As per a media report in The Indian Express, reacting to Ghosh’s arrest, the father of the junior doctor who was raped and murdered said, “While I’m relieved by the CBI’s arrest, there’s no true solace. I would still say there is nothing to celebrate for me. However, we welcome the arrest.”

On Wednesday, the Indian Medical Association (IMA) of Kolkata suspended the membership of former Sandip Ghosh amid a CBI probe into the corruption case, news agency ANI reported.

Earlier on August 26, the CBI also concluded a second round of polygraph tests on Dr Ghosh as part of their investigation into the rape-murder of a woman doctor at the institution.

The Calcutta High Court has granted the CBI three weeks to submit a progress report on the investigation, which is to be presented on September 17.

Earlier in the month, the Supreme Court ordered the security of Kolkata's RG Kar Medical College and Hospital to be handed over to the Central Industrial Security Force (CISF) while hearing the suo motu case concerning the incident.

The trainee doctor was found dead in the seminar hall of RG Kar Medical College and Hospital in Kolkata on August 9.
