However, it should not be about life-threatening injuries.
-One person is suspected of having injured two other people.
All involved are young boys between 15 and 18 years old, says police spokesperson Helena Boström Thomas.
It is unclear what preceded the assassination attempt, but there was some kind of riot at the scene and several people witnessed the incident.
Both boys have been taken to hospital but the other boy has minor injuries.
The suspected perpetrator was arrested at the scene after several witnesses alerted the police.
