Greenvale Secondary College was plunged into lockdown when two students were injured in an alleged affray which began about 3.12pm yesterday.

Police arrested a 16-year-old girl and she was interviewed in relation to attempted armed robbery and affray.

She was spoken to at a police station yesterday evening and has been released pending summons.

Police are investigating after five people allegedly approached students outside the school on Glencairn Drive.

A scuffle broke out and two students sustained minor injuries, police said.

“Police believe one person produced a machete at the scene but it was not used in the affray,” officers said in a statement.

Bystanders filmed the alleged attack, which showed punches being thrown between a group of people.

The five alleged offenders left the area in a car and have not been located.

Police have described it as a “targeted” incident.

Ambulances were called to the incident, however no emergency treatment or hospital transport was needed.

In an email to parents, the school’s principal said the college was put into lockdown but assured them students and staff are safe.

Police have appealed for anyone who may have filmed vision of the incident or who may have information to please come forward or contact Crime Stoppers on 1800 333 000.
