Dramatic footage has captured the moment a mass brawl erupted inside a college in front of terrified students.
Distressed witnesses can be heard screaming fear as yobs hurl punches at one another in Sandwell College, West Midlands.
The cause of the fight is not clear but as the violence escalates, chairs are tossed across the room, hitting at least one boy in the head.
At one point in the melee, it appears a boy is repeatedly stamped on after he is knocked to the ground.
The footage, taken by one onlooker, shows a large number of teenagers squaring up to each other inside the state-of-the-art campus.
