"STF probe into the MPPEB scam is totally helpless ("laachar") and is aimed at protecting the Chief Minister, his family, influential politicians and officials close to him," Singh said after meeting the STF chairman Justice Chandresh Bhushan here.
STF was formed only recently by the Madhya Pradesh High Court after Singh filed a petition demanding a CBI probe into the scam where the entrance examinations for professional courses were allegedly rigged.
He also alleged that the computer hard disks seized from the possession of MPPEB officials were tampered with to save some influential people.
He warned the STF officials that under the Information Technology Act, tampering with hard disks is a crime, cases can be registered under the act and can lead to prison terms.
The former Chief Minister said he was going to set up a toll-free number at his residence so that people can give information about the MPPEB scam, the MP Public Service Commission scam and the mining scam.
Identity of the caller will remain confidential, he said.
