It was at 7.30 pm on Friday night that the quarrel broke out for unknown reasons.

- There were several who called us about the quarrel. No person should have been injured, but at least one car has been damaged. We have arrested a man who is suspected of a serious illegal threat, says Björn Öberg, press spokesperson for the police.

The suspect is in his 60s, and a drunk man of the same age was taken into custody for sobriety. Two iron pipes and a knife have also been seized. The incident will now be investigated by the police.
