In a significant development in the alleged forged signatures case involving Trinamool Congress (TMC) legislators, a team of the Criminal Investigation Department (CID) on Tuesday reached the party’s central office, which also serves as the Kalighat residence of TMC chief Mamata Banerjee. According to the information, officials from the state investigating agency arrived at 30B Harish Chatterjee Street around noon. The team was accompanied by personnel from the Kalighat Police Station as well as a sizeable contingent of women police officers. The visit is linked to the CID’s ongoing investigation into allegations that signatures of several TMC MLAs were forged on a proposal submitted to the West Bengal Assembly Speaker regarding the recognition of the Leader of Opposition.
