Chowdhury, who represents West Bengal's Malda South Lok Sabha constituency and is brother of late Congress leader Ghani Khan Chowdhury, was subject to interrogation for nearly three hours by the Special Crime Branch of CBI probing the multi-crore Saradha scam.
CBI sources told PTI that Chowdhury was asked why he withdrew his letter to the PM, to which he replied, "I did that because these firms, including Saradha, were doing real estate business and not working as chit funds raising money from the public."
