National Commission for Protection of Child Rights (NCPCR) Chairperson Priyank Kanoongo has alleged that a West Bengal police officer named Biswak Mukherjee manhandled and beat him up at Tiljala Police Station. He claimed that the incident occurred when he objected to police officers "secretly" recording NCPCR's investigation. Notably, NCPCR's probe was regarding sexual assault and murder cases.
