Two Australian men are being treated for serious stab wounds in Bali following a fight at a bar.
The two men were allegedly stabbed about 2am (0500 AEDT) on Friday morning during an altercation at the Bounty Discotheque on Jalan Legian, the main street in a popular nightclub area near Kuta Beach.
One of the men has been identified as Jake Benjamin Whitehead.
Bali Police spokesman Hariadi could not provide a last name for the second victim, identifying him only as Chris.
Two local people whose identities were not known were also injured in the fight.
Hariadi said the fight broke out after the alleged attacker spilled a drink that belonged to one of the victims.
"He was asked to replace the drink, but then he got angry and there was a fight between the perpetrator and the victims," he said.
"In that fight, one victim was stabbed in the stomach while the other one was cut on his chest and armpit."
Another police officer, who refused to be named, said the two Australian men were still in hospital and described their wounds as serious, although not life-threatening.
"We have not been able to ask for an explanation from the victims because they are still hospitalised," he said.
Mr Whitehead was being treated at the Bali International Medical Centre in Kuta while the man identified as Chris had been taken to Sanglah Hospital in Denpasar.
Hariadi said the identity of the attacker was not yet known, but that he was believed to be a foreigner.
"The police are still investigating the case. The police are still looking for the perpetrator and trying to establish his identity," Hariadi said.
The bar where the incident occurred is the same place where former North Melbourne AFL coach Dean Laidley was hit over the head with a bottle in October and his son left with a broken jaw following a fight.
It is also near where an Australian teenager was electrocuted early this month while walking along the street.
In 2009, a 22-year-old New Zealand man was killed after being attacked in the nightclub by two employees and another man, all of whom were later convicted of murder.
Bali, and the Kuta area, is becoming increasingly popular as a destination for Australian teenagers taking part in "Schoolies" celebrations.
