Kolkata/ New Delhi, Dec 23 (ANI): BJP said that Trinamool Congress party has fallen into its own trap while saving its party leaders in Saradha chit fund scam. Minister of State for Parliamentary Affairs, Mukhtar Abbas Naqvi said this after suspended TMC leader Kunal Ghosh claimed that party Chief Mamata Banerjee, is involved in Saradha chit fund scam. Earlier in the day, a delegation of Left parties also submitted a memorandum to Prime Minister Narendra Modi, demanding a coordinated investigation into the scam and compensation for the victims. However, while addressing an event in Kolkata, Banerjee took an indirect jibe at BJP, saying the party possesses pessimistic attitude. However, TMC leader Derek O'brien refuted Ghosh's claims.
