The Supreme Court on Monday asked CBI to collect all relevant material and evidences to pursue case against people accused of framing ISRO aerospace scientist and Padma Bhushan awardee Dr Nambi Narayanan in 1994 espionage case after the agency told the court that it had registered an FIR in the case.

A bench of Justices A M Khanwilkar and Sanjeev Khanna said that CBI should not just proceed only on the basis of report filed by court-appointed Justice D K Jain committee and it had to proceed as per the procedure.

Former Kerala police chief Sibi Mathew, who has been named in the FIR along with other 16 people, pleaded the court that the CBI should provide all relevant documents including FIR in trial court so that he could pursue his remedy.

Solicitor general Tushar Mehta, appearing for the agency, assured the court that the FIR would be uploaded during the course of the day.

"CBI can proceed after registration of FIR... as per law and no directions required from this court. The respondent can take all possible remedies available in law... After registration of FIR, CBI must collect material on its own and not proceed on basis of report submitted by Jain committee which cannot be the sole basis for CBI to pursue the case," the court said.
