A US national has surrendered to police after a 42-year-old Australian man was beaten to death in a brutal bar fight at a seaside resort in southern Thailand.
Benjamin Robb, from Newport in Victoria, had just begun a trip to Thailand when he became involved in a drunken brawl at the Ruby Club bar in Pattaya, 150km southeast of Bangkok, last Friday evening.
Thai media reports say the fight was between Mr Robb and an unnamed American, said to be about 30 years old.
Mr Robb was reported to have been acting aggressively towards the American and other staff at the bar before the altercation occurred.
Witnesses said Mr Robb was allegedly beaten, thrown across the bar and stomped on resulting in major injuries to his head and upper body.
The American initially fled the scene but later turned himself over to Thai Police.
Thai paramedics and police were quickly on the scene and Robb was taken to the nearby Pattaya Memorial Hospital. But despite treatment he died in the early hours of Saturday from his injuries, including internal bleeding.
Eyewitnesses said both men had been drinking heavily in the afternoon and appeared intoxicated when the fighting broke out.
The Ruby Club, in a statement, said the altercation had been brief and had left the Australian unconscious. The American, the statement said, was expected to be held in jail for at least 10 days before an initial court appearance.
Thai police said they would be carrying out a thorough investigation.
Eyewitnesses said some bars in Pattaya are popular among those involved in weight lifting and martial arts sports in Thailand.
The Australian Department of Foreign Affairs and Trade (DFAT) is offering support to the Robb family.
