Police were called to Napier Boys High' School this afternoon after an apparent assault on a student by one of up to three young males who came on to the school grounds.
School principal Matthew Bertram said a student was punched before the offender was "locked-down" by another student.
Police confirmed they were called about 2.30pm, and while investigations were continuing no one had been arrested by late afternoon.
Bertram said the incident appeared to be "over a girl".
The student was being supported at the school awaiting the arrival of a parent, while extra staff were present on the Chambers St frontage of the school to monitor after-school activity outside Hawke's Bay's biggest school, which has a roll of about 1200.
