The Trinamool Congress leader, who was in jail for nearly two years for his alleged involvement in the multi-billion rupee Saradha ponzi scam before getting bail on September last year, appeared before the agency at Nizam Palace here at around 11 a.m. on Wednesday.
Mitra, however, remained tight lipped about the interrogation stating that he came there to help in the investigation and have given the necessary details to the Central Bureau of Investigation.
"I came here because CBI summoned me and have given them whatever information they asked for. I cannot divulge the details to anyone else. I will come again if they summon me in the future," he said after the interrogation.
The agency lodged an FIR on April 17 against 13 persons, including several state ministers and MPs from the ruling Trinamool, a month after the Calcutta High Court ordered a preliminary inquiry into the Narada sting footage case.
They have already interrogated many of the accused in the case.
The controversy erupted in election-bound West Bengal in March last year when Narada News portal uploaded a video clip purportedly showing the Trinamool leaders receiving money for extending favours to a fictitious company.
