Lok Sabha MP and leader of Trinamool Congress parliamentary party Sudip Bandyopadhyay arrived at the CBI office in Kolkata on Tuesday for questioning in connection with the Rose Valley chit fund scam.
This is the first time that he would be grilled in the matter soon after another party MP Tapas Pal was sent to police custody in the case.
When asked, Bandyopadhyay told reporters, "I said I will come to face CBI interrogation to know what is against me".
He also alleged political vendetta against him and the Trinamool Congress party by the NDA-ruled Central government.
Rose Valley scam, which was also being investigated by the Enforcement Directorate, encompasses a larger amount of money swindling as compared to the Saradha case.
