Anna University Vice Chancellor M.K. Surappa on Friday said that the marks-for-money scam had been reported only from affiliated colleges, not from the varsity campuses.
Surappa told reporters here that none of the varsity campuses was involved.
The varsity has suspended its former Controller of Examination G.V. Uma, a Professor in the Department of Information Science and Technology, for the irregularities reported in the re-evaluation of engineering examination answersheets, officials said.
Tamil Nadu Minister for Higher Eduction K.P. Anbalagan told reporters that evidence was being collected against the suspects.
PMK founder S. Ramadoss has demanded a probe into the role of private engineering colleges as well as former Vice Chancellors and Education Department officials in the scam.
Investigating a complaint regarding irregularities in the re-evaluation of answersheets, the Directorate of Vigilance and Anti-Corruption (DVAC) had registered a case against seven varsity officials, including Uma.
