The police are investigating reports from the victims that the Hell Angels were behind the attack which took place in the early hours of Saturday morning.
The three injured parties, who are all men aged 25-30-years-old, were taken in private cars to the hospital, where the police were informed of the incident.
It remained unclear to which motorcycle gang the injured men belong.
“I have no information about that,” said Ulla Brehm at Västra Götaland police.
The Hell Angels have been linked to similar attacks in recent months.
In early May 18 men linked to the gang attacked a biker party outside Kalmar in southern Sweden, assaulting eight people with punches, kicks and weapons.
“There have been a number of incidents where they have strayed into someone else’s territory,” said Lars Öjelind, the national police commissioner for gang-related crime, to the TT news agency.
Öjelind is not familiar with the latest case in Skene, but explained that tension has been building between the rival gangs throughout the summer and autumn.
“But it’s been up and down. Right now it’s been pretty quiet for a while, as far as we can see. But it is a tense situation between a number of these kinds of groups,” he said.
No one has yet been arrested in connection with the attack in Skene. Police have classified the incident as attempted manslaughter.
A forensic examination of the premises was conducted on Saturday as well as several interviews with witnesses.
