Sandip Ghosh, former principal of RG Kar Medical College and Hospital, and Abhijit Mondal, the former officer-in-charge of Tallah police station, were granted bail by a special court in Sealdah on Friday in the RG Kar Medical College and Hospital rape and murder case.

The duo was granted bail after the Central Bureau of Investigation, which is probing the rape and murder of a postgraduate trainee doctor at the state-run healthcare facility in Kolkata on August 9, failed to submit chargesheet within the stipulated 90 days.

CBI sleuths had arrested Ghosh and Mondal on September 14 on charges of “destruction of evidence” in the case that rocked Bengal and the country and sparked widespread protests spearheaded by the junior doctors.

The victim’s body was found in a seminar hall of the emergency building of RG Kar medical College and Hospital in north Kolkata.

On Friday, when the case came up before the additional chief judicial magistrate’s court, the CBI’s counsel informed that the central agency would need more time to frame the chargesheet in the case.

The additional chief judicial magistrate granted bail to both the accused.

Ghosh will remain in CBI custody as he is also accused in another case, on alleged financial irregularities in the medical college during his tenure as principal.

The Bharatiya Nagarik Suraksha Sanhita allows 15 days of police custody, which can be authorised in parts during the initial 40 or 60 days of the 60 or 90 days period of judicial custody.

The role of Ghosh and Mondal came under the scanner as the autopsy on the victim was carried out before the FIR was filed in the case.

Doctors demanding justice for their colleague had alleged that the hospital authorities and the Kolkata Police had together destroyed evidence in the case.

Then Kolkata Police chief Vineet Goyal had vehemently denied the allegations.

Mondal was accused of delay in filing the FIR, which also came up for discussion during the hearing before a Supreme Court bench headed by then chief justice of India D.Y. Chandrachud.

Mondal's lawyer told reporters outside the court on Friday that he will walk out of the correctional home where he is incarcerated on judicial remand.

The family members of the RG Kar victim are unhappy with the progress in the case as the CBI – which was handed over the probe following an order by Calcutta High Court – has not made any more arrests in the case.

The trial of Sanjoy Roy, the lone accused in the rape and murder of the post graduate trainee doctor, is ongoing.
