A 22-year-old man has been arrested after an elderly man was bashed and robbed during a pre-dawn walk in Sydney’s south-west.

The 76-year-old was walking along Chester Hill Road in Bass Hill about 5.45am on Sunday when he was confronted by a man who allegedly pushed him into a fence and hit him in the face.

He fell to the ground and was beaten by his alleged attacker before stealing cash from his wallet and running off.

The victim managed to walk to a nearby shopping centre and was taken to hospital with deep wounds around his eyes, chin and finger.

The 22-year-old Rockwood man was arrested at 3pm yesterday and is expected to be charged.
