It's unclear when the footage was taken. VCE exams began on Monday and last week was the end of the school year for many Year 12 students, including those at Northcote High. In the video, a person can be seen running across the oval past students before scaling a fence and jumping onto the corrugated tin roof of a building. The person then lets off several flares on the roof and throws one into a playground full of students, before they jump from building to building on the roof. They then leap to the ground, scale a barbed wire fence and leave the school grounds via a back lane.

The individual, who is not wearing a school uniform, appears to have their face covered with a black hoodie. The video has garnered almost 2000 likes and more than 400 comments in the private Facebook group. The person escapes by scaling a barbed wire fence.

"I am disappointed by the behaviour of a very small number of our students during last week’s end of year celebrations," she said.

"There is no place for anti-social behaviour that puts others at risk and this behaviour marred an otherwise positive day. Thankfully no students or staff were injured." It's understood students involved in the incident are set to face disciplinary action. It appears the footage was taken on GoPro camera.

It's not the first time flares have been lit during muck up day at a Melbourne school.
