Police say it is lucky no one was killed following an organised fight between two 15-year-old girls in Auckland.
The fight, watched by up to 50 people, occurred at a bus depot in the suburb of Onehunga last week and only ended after police were forced to pepper-spray the pair.
One of the girls, a student from Auckland Girls' Grammar, was slashed across the neck with a broken beer bottle, police say.
Senior Sergeant Hirone Waretini told Checkpoint that someone could easily have been killed and if the weapon had struck a main artery, it is likely police would now be dealing with a homicide.
Mr Waretini says a 15-year-old girl from Onehunga has been charged over the incident.
Police say they are keeping an eye on students who congregate at the bus depot and are talking to local schools.
