The Directorate of Revenue Intelligence (DRI) and the Border Security Force (BSF) conducted the operation in the Charianantpur area of Malda yesterday.
"The DRI had gathered intelligence about the movement of fake currency notes. Asikul Sekh was intercepted with 198 fake bills of Rs 2,000 when he was boarding a train. He was arrested by DRI sleuths," a senior official said.
Sekh is a resident of Charianantpur.
A joint search was subsequently conducted by the DRI and the BSF in that area for further leads, a senior official said.
