A shocking video shows a student throwing a punch at his classmate, only to be brutally picked up and body slammed in response.

The 26-second video, believed to be filmed in the U.S., has racked up nearly 100,000 views since it was posted to YouTube on Friday, although it remains unclear exactly where it took place.

A crowd of what appear to be high school students are shuffling down a hallway when the confrontation turns violent and ends with one student on the ground.

The clip starts off with one boy in a black t-shirt, appearing to taunt a shorter classmate.

The two continue along the hallway surrounded by other students, when the boy in the black t-shirt walks ahead, turns around and suddenly throws a punch.

But it isn’t long before that turns out to be a grave mistake – the shorter boy then picks up his adversary and flips him onto the ground.

The crowd reacts in shock as the shorter boy then punches him once.

The student who threw the first punch ended up motionless on the ground. It remains unclear if he was seriously injured.
