CBI DIG Gagandeep Gambhir has been shifted to the unit which is probing the Srijan scam as also the case against journalist Upendra Rai. She will also have the charge of DIG in Special Investigation Team (SIT) headed by Joint Director Sai Manohar, the sources said.

The SIT, which was earlier headed by Rakesh Asthana, is probing cases like that of Vijay Mallya and AgustaWestland.

Interim director M Nageshwar Rao, who was given the charge after a High-Powered Committee of Prime Minister Narendra Modi, Justice AK Sikri and Mallikarjun Kharge shunted CBI director Alok Verma out past Thursday.

As far as the probe in the illegal sand mining case is concerned, it would now be supervised by DIG Anish Prasad. Prasad held the charge of Deputy Director (Personnel & Admin) before this.

Asthana was sent on a forced leave after the CBI registered a case of corruption against him. His plea to quash the FIR was rejected by the Delhi High Court.

Meanwhile, the post of the Director of Prosecution is also lying vacant and the Centre has sought nominations from different ministries to expeditiously fill vacant it. OP Verma, who served as the Director of Prosecution, completed his term on December 23, sources said.

The Director of Prosecution is a crucial post in the federal probe agency. The incumbent, who works under the supervision and control of the CBI Director, renders legal opinion in all the cases probed by the agency, the officials said.

The Personnel Ministry has written to secretaries of all government departments for names of eligible and willing officers, not below the rank of Joint Secretary and eligible for appointment as Special Public Prosecutor, they said.
