DVAC sleuths said that Radhakrishnan, who was the VC of newly formed Anna University, Coimbatore, in 2008-09, in 2008 demanded bribe to sanction a tender in favour of Senthil Kumar, a furniture vendor from Erode. Meanwhile another vendor, Mohammed Iqbal of Coimbatore, came forward to supply the furniture for a lesser price. The order for 750 dual desks and benches was split among the two. Mohammed Iqbal supplied 500 of them and Senthil supplied the remaining 250. DVAC sleuths said that the VC passed the cheque for the first vendor, but stopped the payment for Senthil as he had not given the bribe. The payment was released after he paid Rs 40,000 to the VC.
