The West Bengal Criminal Investigation Department (CID) is probing a signature forgery case involving 13 MLAs from the Trinamool Congress (TMC). The investigation was initiated after complaints were filed alleging irregularities in a resolution concerning the appointment of party leaders, including Sobhandeb Chattopadhyay as Leader of Opposition. Three MLAs have stated that their signatures in the Meeting Resolution Book from May 6 were not authentic. The CID has summoned TMC general secretary Abhishek Banerjee to present the original resolution book. The allegations surfaced after two TMC MLAs claimed that the resolution was fabricated, with discrepancies in the signatures. Following the complaints, the TMC suspended the two MLAs for anti-party activities. The CID took over the investigation on May 28 after the Hare Street Police registered a case under various sections of the Bharatiya Nyaya Sanhita related to cheating and forgery.
