KOLKATA: National Commission for Protection of Child Rights chairperson Priyank Kanoongo claimed that he was roughed up by police officers while visiting the residence of a minor girl in Kolkata’s Tiljala area, who was killed by a neighbour earlier this week. Police rubbished Kanoongo’s allegation and said officers had cooperated with him, and it was the NCPCR chief who “misbehaved” with them. “Bengal police officer Biswak Mukherjee beat me up at Tiljala police station in West Bengal. Policemen were secretly recording our investigation proceedings. They beat me up for protesting against this,” Kanoongo tweeted on Friday. Meanwhile, West Bengal Commission for Protection of Child Rights chief Sudeshna Roy claimed that Kanoongo insulted her and her colleagues, and that she was contemplating lodging a police complaint in this regard.
