CBI sources said that Nabarun Dutta, Jasim Hossain, Jasmir Hossain and Ajgar Ali were arrested for allegedly misappropriating crores of rupees collected from gullible investors.
The FIR against the group was registered last year upon a directive from Supreme Court.
The firm is considered to have been one of the top-five chit fund companies that were once operating in West Bengal.
