Man in coma after Sydney service station 'assault'

The hunt is on for a man suspected of bashing another man at a service station in Sydney's west.

The alleged attack took place outside a petrol station on Vaughan Street in Lidcombe about 10.30pm yesterday.

The suspected attacker bought a soft drink, noodles, and a winning scratchie ticket.

"The guy came to the service station to get the stuff — and he just brought the stuff and he was walking out and he get into an argument with another guy," one witness said.

"They just started punching each other," the witness said.
