Tavde tipped off the ACB, which laid a trap. However, the meeting was called off as Katkar got suspicious. He then agreed to meet Tavde in a restaurant at Shivaji Chowk in Kalyan. The ACB team, comprising deputy superintendent Jabir Sheikh and inspectors Ashok Jagtap, C N Thorat and P G Suikar, nabbed Katkar even as Tavde was handing him the marked notes. The ACB also raided the sewerage department, and a detailed search was on at the time of going to press.
