He was trapped by a DVAC team led by M B Natarajan and S Thirunavukarasu, after assistant executive engineer, Selvam filed a complaint, alleging that the duo demanded Rs 4 lakh when he pleaded for revocation of his suspension.
Ironically, Selvam had been placed under suspension on charges of bribery about 15 days ago.
Srinivasagan, was caught red-handed while accepting Rs 2 lakh. Further, a three hour search at his residence in West Mambalam yielded Rs 22 lakh in cash.
