Video has emerged of a boy using his body to block a vicious attack on a girl in Whakatane.
The film was posted to Facebook about 6pm on Wednesday and had been viewed more than 450,000 times by this morning.
Trident High School principal Philip Gurney confirmed some of the students attended his school, however, another attended a different local high school.
"Fortunately we don't have issues like this happening on a regular basis ... it's a group of students; some of them are from our school, some of them are not at school, and some of them are from a different school."
He told the Herald the girls involved had been stood down from school and the boy had been commended for his actions.
