They said about 1am, a 23-year-old man, his girlfriend and another friend left a nightclub in Victoria Street, reportedly arguing with each other at the time.

As they reached the intersection with Victoria Street, a silver coloured Mercedes travelling north on Denison stopped.

Three male offenders, described as ‘‘Australian’’, jumped out of the car and demanded the victim give them money.

The man was hit in the back of the head and had his wallet taken, while the victim’s friend suffered scratches to his arm and face.

The offenders drove off in an unknown direction.
