A primary school teacher, identified as Saikat Chatterjee, was allegedly attacked by "TMC goons" after he objected to the display of an advertisement featuring CM Mamata Banerjee at a Voter Training Centre in West Bengal's Ranaghat, the BJP claimed. "This [advertisement] breached the Code of Conduct," Chatterjee said in a video. The staff mercilessly beat him up, the BJP said.
