Matthew Douet, named in court papers as the current secretary of the South Coast chapter of the Comancheros outlaw motorcycle gang, is alleged to have coward punched the victim after he refused to buy Douet a drink.

Court documents said Douet, 29, was at the pub with friends watching a boxing match on the afternoon of July 21 when he approached the victim and said "I heard you're in the Reich".

The 51-year-old man replied "nah mate, who told you that?"

Douet allegedly said "a couple of the lads in there, are you sure you're not in the Reich?"

He then said "don't worry about it, I'm in the Comancheros."

The victim said "oh cool", at which time Douet allegedly said "go buy me a beer".

The victim said he didn't have the money to buy Douet a beer, prompting Douet to allegedly reply "I don't care, go buy me a beer".

When the victim again refused and turned away, Douet allegedly punched him in the head from behind, causing the man to fall unconscious to the floor.

"As a result of the assault the victim suffered a large, open laceration to his nose as well as bruising and redness to his face," court documents said. Douet immediately left the hotel. The victim was taken to hospital for treatment.

When police arrested Douet on Wednesday morning, he allegedly told them "I don't even remember, I was so drunk".

Douet was charged with affray, assault and participating in a criminal group.

He sought release on bail in court on Wednesday afternoon, saying he ran a pedigree dog breeding business from his home and needed his liberty to look after the animals.

However, Magistrate Michael Stoddart refused to release Douet, noting the assault appeared to have been unprovoked and had been caught on CCTV.

The case will return to court on August 6.
