Police at the scene of the incident in Sydney airport
A man has been bludgeoned to death by a group of Australian motorcycle gang members in full view of dozens of people at Sydney airport.
Witnesses described bikers swinging poles "like swords" at each other's heads as the brawl spilled over two floors of Sydney's domestic terminal.
Four suspects have been arrested and the others are said to have fled.
Police believe the fight broke out when one group of bikers coming off a plane was ambushed by a rival gang.
Police did not name any gangs thought to be involved, but Australian media reported that the brawl, on Sunday afternoon, was between the Hell's Angels and Comancheros gangs.
A 28-year-old man died in hospital from severe head injuries.
Police said about 15 gang members were involved in the fight, which was witnessed by about 50 people.
'Group of cowards'
Witnesses described how the gang used the metal bollards in the check-in area as weapons.
"They started grabbing the metal poles that break up the check-in area and swinging them almost like swords at each other's heads," Naomi Constantine told Australia's ABC news.
"I saw one of the men lying on the ground and another man came up with a pole and just started smashing it into his head."
Local police chief Peter Williams called the attack a "disgraceful act perpetrated by a group of cowards".
"A group of males have exited a plane and they were met by another group of males who we believe may be other motorcycle gang members," Detective Inspector Williams told reporters.
