The incident occurred last evening at Raninagar high school where some students and their guardians were holding a protest to demand from the government cycles for some of the girl, Superintendent of Police Akash Megharia said.
When the police approached the protest venue to disperse the crowd, a mob of local people - not comprising the students and their guardians - attacked the police with stones injuring two sub-inspectors and damaging as many police vehicles, he said.
