Replying to another query by the court, the agency said it has not yet probed the issue relating to media reports featuring photographs and videos that showed former Bihar minister Tej Pratap Yadav, the son of RJD supremo Lalu Prasad Yadav, along with one of the then absconding accused.
The submission was made by the probe agency before a bench of Chief Justice Dipak Misra and Justices A M Khanwilkar and D Y Chandrachud after it enquired about the status of the investigation in the case.
The counsel for CBI said that the final report has been filed on August 22 before the special CBI court.
When the bench enquired as to whether CBI has probed the issue relating to media reports featuring photographs and videos that showed Tej Pratap Yadav along with one of the then absconding accused, the CBI said it has not probed this yet.
The court then adjourned the matter for eight weeks. The apex court had earlier issued notices to Shahabuddin, Yadav and Bihar government on the plea of Ranjan's wife seeking transfer of the case from Siwan in Bihar to Delhi.
The apex court had directed the CBI to proceed with investigation and ordered police protection to the scribe's wife Asha Ranjan and their family.
Asha had moved Supreme Court seeking transfer of probe and trial in the case to Delhi alleging that media reports had shown two absconding killers of her husband in the company of Shahabuddin and Yadav.
Kaif surrendered in a Siwan district court on September 21.
The scribe, working with a vernacular daily, was shot dead on the evening of May 13 in Siwan town by some sharp-shooters allegedly at the instance of then jailed RJD leader, the plea alleged.
Despite being named by the family of the journalist, Siwan police did not name Shahabuddin in the FIR as a key conspirator, it alleged.
It also alleged that the RJD leader was irked over some reports by the slain journalist on the issue of murder of three sons of Chandrakeshwar Prasad. Shahabuddin has been awarded life term in one of the cases.
