Parents are concerned a gang culture is developing at an Auckland school after a dozen police officers were called to break up a lunchtime brawl.
Police and a police helicopter were called to Aorere College, in Manukau, on Friday afternoon after a fight broke out on the rugby fields.
The Herald on Sunday has been told weapons were involved, including a hammer and a knife.
Police said one student was injured during the fight, believed to be started by five students egged on by dozens of bystanders.
The school did not go into lockdown but head prefects helped keep students calm during the ensuing afternoon classes.
