A man's ribs are broken with a baseball during a gang attack in this brutal footage.
The man was also stomped on and run over in the vicious beating, with CCTV showing three men repeatedly hitting the victim in the middle of the road.
The attack took place at 11.30pm on Wednesday and it is believed around 15 people from five cars took part in the assault.
Footage shows the men dragging the man to the ground.
One of them then raises the bat in the air and repeatedly bashes it down on him.
Another car then speeds into shot and can be seen mounting the pavement and driving over the victim.
Other gang members come to join in, and after the car reverses they can be seen viciously stamping on him and throwing punches.
The victim is currently being treated at hospital with serious injuries.
The attack took place in North Parramatta, Sydney, and New South Wales Police are now asking for witnesses to come forward to help their investigation.
