CBI affidavit says investigation was being done by SIT and crucial evidence such as laptops, mobile phones etc were handed over to the main accused in Saradha scam case by the investigating officer of Bengal police working under direct supervision of Police Commissioner Rajeev Kumar.

Affidavit also states,return of crucial evidence to main accused by the SIT, despite regular monitoring by High Court, clearly show connivance of SIT to a larger conspiracy wherein local authorities obstructed probe and attempted to destroy evidence prior to transfer of the case to CBI by top court.
