A video circulating on social media allegedly shows the terrifying moment a boy pulls a machete from his trousers and wildly swipes the blade at a student.
The unverified footage shows two males in a heated row inside a busy student common room.
Another pupil is seen trying to grab the arm of one of the boys and shouting 'no, no' before he then draws a huge blade from his jogging bottoms and thrashes it against the surface of a table tennis table.
A boy then scurries backward as the machete-wielding pupil circles around the table and swipes at him again, with other students watching on.
He then tucks the blade back into his waistband before marching out of the student hall.
