The Enforcement Directorate has registered a money laundering case against Senthil Kumar, a Bihar cadre Indian Administrative Service (IAS) officer, under the Prevention of Money Laundering Act.

“The case is based on primary investigations by the State vigilance,” official sources told The Hindu on Monday.

Mr. Kumar, who hails from Tamil Nadu, has been under suspension for the past one year, since the State vigilance bureau charged him with violating municipal rules during his tenure as the municipal commissioner of the Patna civic body, a government official said.

The State vigilance had filed a charge sheet against Mr. Kumar for the infraction that reportedly caused the State exchequer a loss of Rs. 8 crore. He was suspended based on the charge sheet.

Three more senior government officers, namely Dhruv Narayan Choudhary, former Rajbhasha director; Awadhesh Prasad Singh, chief engineer of minor irrigation; and Yogendra Kumar Jaiswal, former State drug controller, are also in the Enforcement Directorate net.
