CBI spokesperson said charge sheet has been filed in Additional Chief Magistrate Court in Alipore, Kolkata.
She said the charge sheet has been filed against Sen and Saradha Construction Company Limited and Saradha Realty India Limited under charges of cheating.
The agency is keeping probe open, she said.
This is the 17th charge sheet filed in the chit fund scam which spread across four states-West Bengal, Odisha, Assam and Tripura in which investors were allegedly promised higher returns on fixed deposits.
The companies running the alleged schemes defaulted on payment as they had diverted the money into other businesses.
