West Bengal Chief Minister Mamata Banerjee on Monday alleged that Union Home Minister Amit Shah was responsible for the recent attacks on her nephew and TMC national general secretary Abhishek Banerjee and other party workers, and asserted that she won`t be cowed down by such acts.

Her allegation comes days after Abhishek Banerjee and TMC student activists were attacked in separate incidents in BJP-ruled Tripura, where the party hopes to expand its base ahead of the 2023 assembly elections.
