CBI has registered a case of alleged graft against former Vice-Chancellor of Indira Gandhi National Open University for permitting two varsities to run distance learning courses in violation of norms.

Soon after registering the case against Rajshekharan Pillai, the agency on Friday carried out searches at his premises in Trivandrum and Kottayam.

The CBI has alleged that Pillai during his tenure as VC of IGNOU allowed Sikkim Manipal University and Punjab Technical University to run distance learning courses in violation of laid down procedures, sources said.

They said Mr Pillai has been booked under charges of Prevention of Corruption Act, abuse of official position and criminal conspiracy.
