The CBI on Thursday carried out searches at three locations in Kolkata in connection with its probe into Saradha chit fund scam.
CBI sources said that searches have been carried out at the offices of Saradha group companies from where documents have been seized by the agency.

The agency has recently filed two charge sheets in connection with the scam.
The first chargesheet was filed at City Sessions Court on October 22 against four Saradha group companies and one owned by suspended Trinamool Congress MP Kunal Ghosh and contained the names of accused persons Saradha group chief Sudipto Sen, his associate Debjani Mukherjee and Ghosh.
Another charge sheet was filed in which persons have been named Sen, Mukherjee, former West Bengal DGP Rajat Majumdar, businessman Sandhir Agarwal, East Bengal club official Debabrata Sarkar, Assamese singer Sadanand Gogoi, who were all arrested by the agency.
The chargesheet also contained the name of Sajjan Agarwal, father of Sandhir Agarwal, who had been interrogated but not arrested by CBI. The other three Saradha group companies named in the chargesheet were Saradha Housing, Saradha Gardens and Saradha Tours and Travels.
CBI has registered four FIRs against Saradha Group companies for alleged cheating and duping the people of their money.
