Officials of the Criminal Investigation Department (CID) have expanded the scope of the probe into the veterinary officers’ recruitment scam to include alleged beneficiaries suspected of having secured selection through unfair means. The CID has recorded the statements of many such candidates, some of whom have reportedly confessed to examination malpractice and paying for it. A few are also said to be willing to turn witnesses in the case, sources said. However, CID officials have remained tight-lipped.
