Accused drunken brawler to front court

An allegedly drunk man has been accused of threatening and assaulting a man with a gun after a scuffle at a caravan park on the NSW and Victorian border.

It's alleged that after a fight with two others on Saturday night the man, 22, left the park and returned with a rifle.

"The armed man allegedly threatened one of the males involved in the altercation, before assaulting him with the firearm," police said.

"A struggle ensued between the man and a number of witnesses, before the armed man drove from the scene."

He was charged with 11 offences, including possessing a loaded firearm in a public place after officers found him near a car that had rolled into a ditch near the Buronga caravan park.

He was breath tested and allegedly returned a blood alcohol reading of 0.107.

The man is due to appear before Wentworth Local Court on Sunday.

Investigations continue with assistance from Victorian police.
