When the police arrived at the scene, the noise had ceased and the people involved had left the scene. Later, the police received information that a man had come to the emergency room with stab or cutting injuries and it is suspected that this person was involved in the brawl.
The man's injury situation is unclear.
One person was arrested during the evening at a location other than where the brawl occurred.
"We have a defendant, who came to the hospital, and a suspected offender," says Rickard Lundqvist, press spokesman for the police.
The circumstances surrounding the brawl are still unclear and the crime classification is therefore not determined.
