Teen allegedly stabs NSW guard in back

A 72-year-old security guard has been stabbed multiple times after trying to stop teenagers doing burnouts on an oval in the NSW Southern Highlands.

The guard spoke to two boys and a girl in a car that had been doing burnouts at a Moss Vale oval on Tuesday night, police said.

He then attempted to reach in and remove the keys from the ignition causing one of the teens to get out and attack the man.

The guard was stabbed in his back and hand in the struggle before the teenage boy returned to the car and drove off.

He was taken to Liverpool Hospital with non-life threatening injuries.

Police are looking for the male driver of the red hatchback, believed to be about 17, and his two passengers, believed to be about 14.
