The suspected perpetrator and the victims are known to each other from before, says duty officer Anders Wennergren to TT.
The police were called at 9:17 p.m. on Saturday evening after two people were stabbed by a third person, writes Göteborgs-Posten. The extent of the injuries to those stabbed is currently unclear.
According to the police, all those involved were at the same private event.
The area is cordoned off and police are waiting for technicians.
