SHOCKING video footage shows the moment a man approached an unsuspecting victim and punched him to the side of the head, causing him to fall to the ground, before repeatedly kicking his face.

The CCTV footage captured from a car park in Campsie shows a 27-year-old man, Oliver Goss, was knocked to the ground, and after several kicks, the attacker gives him one final blow — a stomp to the head.

It is one of four assaults police will allege were committed by Ricky Hema, 35, across south west Sydney over a two hour period on January 27.

Burwood Local Court last month heard he was also charged with two counts of assault, occasioning actual bodily harm and causing grievous bodily harm with intent.

Hema allegedly punched a 46-year-old man, Viliame Tagirara, while at the Punchbowl Hotel on Rossmore Ave about 1.30pm. The alleged victim was sitting at the bar when attacked.

He also allegedly kicked and punched 72-year-old, Youssef El-Boustani, outside the pub before getting into his car.

Mr El-Boustani was taken to Bankstown Hospital where he received stitches to the top of his head and treatment for pain to his ribs.

Later that day it will be alleged that the attack in a car park at a block of units in Campsie to Mr Goss occurred.

Mr Goss was taken to St George Hospital with head injuries. Staffs at the hospital were unable to give an update of his condition.

Police will allege Mr Hema then shoulder charged a 46-year-old man, Harley Dimba, outside the Belfield Hotel as he was being ejected, just after 3.30pm.

Mr Hema is yet to enter a plea. He will appear before Burwood Court on March 3.
