CBI Director Ranjit Sinha has denied wrong doings, including giving clean chit to former telecom minister Dayanidhi Maran in the 2G case, claiming before the Supreme Court that a “mole” in the CBI supplied documents and file noting to advocate Prashant Bhushan.

Appearing for the CBI Director, Senior advocate Vikas Singh read out the contents of a confidential 2G scam probe file to deny charges that Sinha tried to save the accused in the case, including Maran.

He said the file noting and documents, on the basis of which the NGO filed the petition seeking probe against the director and his recusal from 2G case, was supplied by a DIG-rank officer Santosh Rastogi.

“It is very clear that Rastogi is supplying all the information. He is the mole in the CBI,” Singh submitted.

During the day-long hearing, the bench wondered if some allegations are made against a reputed trust through a PIL and the court ordered inquiry which proved the charges as false.

“How should we go about it? Should we not ask to disclose the source of information from the petitioner before ordering inquiry? The reputation of the trust would be damaged and it could not be redeemed by imposing cost on the petitioner,” the bench asked.

For their part the NGO Centre for Public Interest Litigation (CPIL) and its council Prashant Bhushan reiterated their reluctance to disclose the source that purportedly supplied the diary containing details of visitors to Sinha’s residence revealing his frequent meetings with the accused.
