The CBI and the Enforcement Directorate (ED) interrogated two Trinamool Congress (TMC) leaders on Thursday as part of the investigation into the Narada tapes scandal.
CBI officials visited the residence of former Minister Madan Mitra at Dakshineswar in the northern fringes of Kolkata to reconstruct the manner in which the Narada sting operation was conducted inside his apartment.
Mr. Mitra, who is also an accused in the Saradha ponzi scam, accompanied the officials and sought to clarify the queries posed by them.
Later, he said he was willing to cooperate with the Central agencies in their probe.
TMC MP Aparupa Poddar, on the other hand, reached the ED office in Kolkata on Thursday to face interrogation in connection with the scam.
Matthew Samuel, CEO of Narada News, conducted a sting operation posing as a businessman and was seen in the tapes offering money to a slew of Trinamool Congress leaders.
