The principal of a Hamilton boys' school has said heavy consequences should fall on six students from a neighbouring girls' school who injured one of her students in a topless trail bike stunt yesterday.
Six students from Hamilton's Waikato Diocesan School for Girls, rode tandem back-to-back on three trail bikes in their underwear through the grounds of Hamilton Boys' High School.
The trail bike escapade lasted for a number of laps of the school in the front playing fields, during which they ran over the leg of one male student, sending him to hospital.
The male student required numerous stitches.
Hamilton Boys' High School Principal Susan Hassall said the trial bike incident was far more serious than some end of year prank.
"It is in my opinion a step more significant than a playful prank," Ms Hassall said.
"There was no regard for the safety of the students on the field.
"There was about 500 boys on the field and they rode trail bikes at excessive speed, hit one boy and left him injured, they didn't stop.
"It was an act that went well above the level of prank. They broke the law so the consequences should be significant."
In a statement, Waikato Police Senior Sergeant Pete van de Wetering said inquiries were being made into the incident, and they had no further comment to make at this time.
Ms Hassall said she did not witness the incident herself but from reports of teachers there at the time the situation was chaotic and totally unmanageable.
"It was impossible to deal with them in any rational way," Ms Hassall said.
While Ms Hassall acknowledged a history of end of year pranks between neighbouring high schools in Hamilton, she said she thought it was something they had been getting a hold of in recent years.
"There has been a history of this end of year prank, but it's something we think we've been successful in changing the psychology of in recent years," she said.
Waikato Diocesan School for Girls was approached for comment.
