Kolkata: The Calcutta High Court has authorized the Central Bureau of Investigation (CBI) to conduct a polygraph test on Dr Sandip Ghosh, the former principal of RG Kar Medical College and Hospital, along with five other individuals connected to the case.

These five include four doctors who had dinner with the deceased doctor on the day the incident occurred, as well as one civic volunteer.

The Calcutta High Court has also transferred the investigation of financial irregularities involving Dr Sandip Ghosh, previously handled by a Special Investigation Team (SIT), to the CBI.

Justice Rajarshi Bharadwaj has ordered the SIT to hand over all investigation documents to the CBI by 10 a.m. on Saturday.

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

Furthermore, the Court directed that the petitioner, Akhtar Ali, may request security from the CBI if necessary.

In a separate development, the Sealdah Court today remanded Sanjay Roy, the main accused in the rape and murder case of the postgraduate trainee doctor at RG Kar Medical College and Hospital, to 14 days of judicial custody. His custody will continue until September 6, 2024, under the supervision of the CBI, news agency ANI reported.

Earlier, on Tuesday, 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 rape and murder of the trainee doctor.

This decision comes amid a period of heightened agitation in West Bengal, with various protests taking place. The deployment of CISF personnel is expected to strengthen security measures and help maintain public order.

Following the Supreme Court's order, CISF personnel have been deployed around the clock to enhance security at the hospital and college complex.
