Leaders and workers of the TMC, including those injured in an alleged attack by BJP workers on the previous day, were arrested in Tripura's Khowai district on Sunday for "violating COVID norms", police said. TMC national general secretary Abhishek Banerjee, who is West Bengal Chief Minister Mamata Banerjee's nephew reached Agartala and left for Khowai to meet the arrested party workers, who will be produced before a court amid tight security arrangements.
