The Central Bureau of Investigation (CBI) conducted searches at seven places in Bhopal including the residential premises of the retired additional director of the Madhya Pradesh Higher Education department, in connection with an investigation into the Vyapam scam.
The searches were conducted at the residential premises of officers who had acted as supervisors in the Transport Constable Recruitment Examination 2012 and the Pre-Medical Test 2012, organised by Vyapam.
These officers are not booked in the scam yet.
According to CBI sources, the searches were conducted at the residences of the retired additional director CL Sharma and principal DS Dakwale.
Both acted as supervisors in the exam at different centres.
The supervisors had allegedly played a role in the tampering of the OMR sheets of some candidates who were fraudulently made to pass the two examinations, said a CBI release.
Incriminating documents recovered during searches are being scrutinised for further investigation by the CBI.
