The Supreme Court on Monday directed the CBI to submit a fresh report by September 17 on the probe in the rape and murder case of a postgraduate medic at Kolkata's RG Kar Medical College and Hospital.

A bench headed by Chief Justice D Y Chandrachud perused the report filed in a sealed cover by Solicitor General Tushar Mehta, appearing for the CBI.

"A status report has been filed by CBI, it appears that investigation is in progress, we direct the CBI to file fresh status report...We don't want to guide the CBI on its investigation," the bench said.

Mehta told the bench also comprising Justices J B Pardiwala and Manoj Misra that the probe agency has decided to send forensic samples to AIIMS for further investigation.

The apex court also directed a senior officer of the West Bengal government's Home department and a senior CISF officer to ensure all three companies of the CISF, which are deputed for security at the RG Kar Hospital, are given accommodation.

It also directed that all requisition, security gadgets needed by the CISF should be handed over to it today.

At the outset, the West Bengal government told the top court that 23 people have died as doctors are on strike protesting the rape and murder of the postgraduate medic.

Senior advocate Kapil Sibal, appearing for the West Bengal government, submitted a status report filed by the state health department.

"A status report has been filed. The state health department has filed a report. Tweny-three people have died as doctors are on strike," Sibal told the bench.

The hearing is still underway.

On August 22, the apex court had tore into the Kolkata Police over the delay in registering the unnatural death of the woman doctor, who was raped and killed at the RG Kar Hospital, calling it "extremely disturbing", and questioned the sequence of events and the timing of its procedural formalities.

The top court had earlier constituted a 10-member National Task Force (NTF) to formulate a protocol for ensuring the safety and security of doctors and other health care professionals.

Terming the incident as "horrific", the apex court had excoriated the state government over the delay in filing the FIR and allowing thousands of people to vandalise the state-run facility.

The alleged rape and murder of the junior doctor in a seminar hall of the state-run hospital has sparked nationwide protests.

The medic's body with severe injury marks was found inside the seminar hall of the hospital's chest department on August 9. A civic volunteer was arrested by the Kolkata Police in connection with the case the following day.

On August 13, the Calcutta High Court ordered the transfer of the probe from the Kolkata Police to the CBI, which started its investigation on August 14.
