New Delhi/IBNS: The Supreme Court on Tuesday said the status report of the RG Kar rape-murder case provided by the Central Bureau of Investigation (CBI) is "worse" and "really disturbing" stating the probe agency will be given time "to unearth the truth", media reports said.

"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 timelimit will be to dislocate the investigation...They are required to be given time to unearth the truth," the CJI added.

Contrary to what CBI has claimed in the court, State's counsel advocate Kapil Sibal said the full video records have been handed over to the central probe agency.

"Mr SG, can you not summon Kolkata police.. and get the footage...you need to see whether hash value changed or not.. CBI has to ensure this.. your investigating officer has to ensure this...make sure that the CBI seizes the entire DVR and footage, we hope that the CBI does it," the CJI said as quoted by Live Law.

Towards the end of the hearing, Sibal told the court that the challan of post-mortem was not used since 1997.

Rejecting Sibal's citation, the CJI said, " We don't buy the explanation, once there is a statutory form, you can't say that it was not used."

Last Saturday, the CBI arrested former RG Kar Medical College and Hospital principal Sandip Ghosh, who was in custody already over financial scams and Tala Police Station OC Abhijit Mondal on charges of tampering of evidence in the rape and murder of a trainee doctor. 

Prior to the handing over the case, the Kolkata Police had arrested civic volunteer Sanjoy Roy in the rape-murder case.
