Young man bashed in another Sydney attack

A young man has been hit in the head and further assaulted after falling to the ground during another late night attack in Sydney.

The 20-year-old was bashed while walking with friends along a main road at Rooty Hill, in the city's west, in the early hours of Saturday morning, police say.

He was punched in the head, fell over, and hit again by the assailant who fled with two other men.

Paramedics treated the injured man for a broken nose before taking him to Nepean Hospital, where he remains in a stable condition.

Clothes found at the scene are being forensically examined.

The attack comes on the same day as the death of Daniel Christie, who was king hit on New Year's Eve.

He had been on life support for 11 days and doctors believed he would have suffered brain injuries had he recovered.

Police are asking anyone with information to contact Crime Stoppers on 1800 333 000.
