Police are now trying to track down the thugs who left the 64-year-old man fighting for his life in hospital.

He was grabbed after getting out of his car when he parked in Newington Street, Enmore, at around 1pm.

He was approached by two men who pulled him to the ground and he smashed his head during the assault.

A witness saw them leaving the area in a dark-coloured hatchback.

The man's wallet was taken and he was rushed to the Royal Prince Alfred Hospital.

His condition has since improved and is now said to be in a stable condition surrounded by his family, according to 7News.
