A 52 year-old man was arrested, for attempted murder and aggravated assault.
For reasons that are still unclear, a fight broke out between the man and several of the other guests, resulting in the man going berserk, and stabbing one person in the stomach.
In the chaos that ensued, several other people were also stabbed, and the 52 year-old was wounded as well.
A total of six people were in the end taken to nearby Skåne University Hospital with knife wounds, but none of the victims have life-threatening injuries, according to police officers.
The 52 year-old was arrested, but due to the head injuries he received during the fight was among those brought to the hospital.
He is suspected of attempted murder and aggravated assault, according to Lund police.
Police are still working to establish the cause of the knife fight. Several witnesses have already been questioned about the event, and when possible, the victims who are currently in the hospital will also be interviewed.
