Another accused in the case, Amit Sen was arrested from Entally on Tuesday. Deputy Commissioner of Police, Detective Department, Jawed Shamim said several tracing papers and duplicate stamps of the state government were recovered from him. “He is an accomplice of Chatterjee and had helped him in forging various documents,” added DC.

With four persons arrested earlier, seven arrests have been made so far in the case, the police said. “Chatterjee seems to be the kingpin of a forgery gang,” said a senior officer of the anti-bank fraud section of the Detective Department. Sources said that he was arrested by the Kolkata police on charges of forgery nearly four years ago.

The economic offence wing of the CBI was hunting for him, as he had been duping various banks since 2006. “Chatterjee had cheated UCO bank and Canara bank with crores of Rupees,” said a CBI source. The Kolkata police had received a complaint to this effect from the Karnataka bank in last December. “To catch him, we conducted raids at several places throughout the country,” said Shamim.

“He deposited the papers of a flat in the Sayeed Amir Ali Avenue as security and took huge loans from several banks,” added DC.

Rashika was the owner of Ma Karunamoyee Films Ltd, that produced films and serials, said the police. Chatterjee was the promoter of a company, Amtech Universal. The duo had recently produced a Bengali film, Greftar.
