The fight occurred on April 18 and was captured in a 30-second video clip by a student with his smartphone.

The video, posted online, has gone viral.

It is unclear what sparked the argument between two boys, both aged 16.

The video also shows a student with a college uniform only witnessing the fight without trying to take control of the situation or step in between the two. He only became peacemaker after the last “knee strike”.

After the video went online, a police report was lodged by the victim’s parents today.

Labuan police chief Muhamad Farid Ahmad said an investigation was being carried out.

He said police had recorded a statement from the victim.

“We have yet to obtain full details on the incident from the college authorities. We will question all involved in the video.

“We advise members of the public not to continue sharing the video footage on social media.”
