Kolkata: A Kolkata court on Thursday sent Saradha Group Chairman and Managing Director Sudipta Sen, company's director Debjani Mukherjee and another official Arvind Singh Chauhan to 14-day police custody in a chit fund scam case.
They were brought to Kolkata late on Wednesday night on a 4-day transit remand.
Congress and Trinamool Congress (TMC) activists reportedly protested outside the court on Thursday.
Congress workers earlier staged protests at the Kolkata airport after Sen and others were brought here.
Sen has claimed that he was blackmailed and used by politicians mainly from West Bengal's ruling TMC.
In a letter to the Central Bureau of Investigation (CBI), Sen reportedly said he was forced to think of committing suicide as he was being blackmailed by influential politicians who were extorting money from him.
He said he is neither liable nor has the money to refund investors.
Among the 22 names that Sen has listed in the damning 18-page letter is that of TMC MP Srinjoy Bose along with "senior politicians" from Delhi, media reports said.
Bose however has refuted the charges and said even though he did do business with Saradha Group companies, their deals ended last year in May after Saradha's cheques kept bouncing.
Sen also has named the lawyer wife of a senior Congress minister in the Centre whom he had to pay along with an influential Congress MP from the northeast region.
The revelations came even as West Bengal Chief Minister Mamata Banerjee on Wednesday announced a Rs 500-crore relief fund for small and medium-term investors who lost money in the chit fund scam of the Saradha Group that went bust last week leaving lakhs of depositors in a fix.
Banerjee has also denied the involvement of any TMC leaders into the chit fund scam.
The Jammu and Kashmir Police on Tuesday arrested Sudipto Sen, Saradha Group director Debjani Mukherjee and another official Arvind Singh Chauhan in connection with the chit fund scam in West Bengal.
Sen was absconding since Saradha Group collapsed recently.
