Soon after her Finance Minister Amit Mitra was heckled by the CPI-M and SFI activists in New Delhi, West Bengal CM Mamata Banerjee took on the Left Front and vowed not to surrender before hooliganism. As a result, the Trinamool Congress cadres attacked the CPI-M offices elsewhere in the state.
Amit Mitra was attacked from all sides. His shirt was torn off. He was reportedly slapped and punched and had to be admitted to the AIIMS later after complaining of chest pain. The BJP tried to add fuel to the fire by coming out in support of Mamata Banerjee and blaming the Centre for the security lapse, which led to the attack on TMC leaders.
