On a tip-off, Pradip Gogoi, a former armyman and a resident of Assam's Dibrugarh district, and his accomplice Sudhir Sarkar alias Sudhir Mondal were arrested by the CID Special Operations Group late last night from Darjeeling More under Pradhan Nagar police station, the official said.
Fake currency notes with a face value of Rs 44,000 were seized from their possession, he added.
"We were looking for the two for quite some time. Both of them played important roles in the FICN racket. They were involved in smuggling FICN to the north-eastern states," the CID official said.
