Horrifying footage has emerged online of a schoolyard fight, with one boy left lying motionless on the ground after being hit in the head.
The clip appears to have been filmed by a fellow student on a phone, with a large group of kids hanging around the two engaged in the fight.
After a few blows were exchanged on both sides, a big hit is delivered, with voices heard yelling "run away" after realising the boy was not moving.
A 7 News journalist has claimed that it took place at a Sydney school, with the boy lucky not to have died.
