Kolkata/IBNS: Trinamool Congress MLA Nirmal Ghosh on Monday appeared before the Central Bureau of Investigation (CBI) in connection with the case pertaining to the rape and murder of a 31-year-old trainee doctor at Kolkata's RG Kar Medical College and Hospital.

Ghosh, who is an MLA from Panihati, arrived at CBI's CGO Complex office located in Salt Lake at 10:30 am.

The ruling party leader is accused of playing a role in hasty final rites of the victim, whose rape and murder have triggered massive outrage across India.

The administration's role has come under the scanner over police's alleged cover-up of the incident.

After the Kolkata Police arrested civic volunteer Sanjoy Roy in connection with the crime, the CBI, which was given the charge of the case by the Calcutta High Court four days after the crime was discovered, arrested former RG Kar principal Sandip Ghosh and a lower level police officer. 

The next hearing in the Supreme Court is scheduled to be held on September 27.

'CBI not sleeping over the probe'

In its third hearing, the Supreme Court earlier this week said the status report of the RG Kar rape-murder case provided by the CBI is "worse" and "really disturbing" stating the probe agency will be given time "to unearth the truth".

"What the CBI has revealed in the report is worse, really disturbing..What you are flagging is of utmost concern, we ourselves are concerned, CBI has flagged it for us..we are ourselves disturbed by what we have read," Chief Justice of India DY Chandrachud said.

A three-judge bench led by the CJI said the CBI is not "sleeping over" the probe and the investigating agency has responded to the issues that the court has flagged.

The CJI said as quoted by Live Law, "Making a disclosure today of what the CBI is investigating will jeopardise the process, the line which is taken by the CBI is to unearth the truth.. the SHO himself has been arrested... CBI has responded specifically to the issues we have raised, including whether the challan in the statutory form was submitted along with the postmortem...

"CBI is also exploring the possibilty of whether the scene of the crime was tampered with, evidence was destroyed, whether there was the complicity of other persons in failing to report the crime etc..."

"The CBI, apart from performing its independent investigation, is also addressing the issues we raised. There is still time to complete the investigation. We have to give CBI adequate time, they are not sleeping over. To put any time limit will be to dislocate the investigation...They are required to be given time to unearth the truth," the CJI added.
