The background to this is something we do not know at present. There is no information that weapons were used, but it involves kicks and punches, says the police's press spokesperson Jimmy Modin to the newspaper.
In total, seven people were subjected to violence and according to the police, two of the cases involve severe violence.
The preliminary picture of the event is that two people were first assaulted outside the hostel and that the perpetrator then entered the hostel and attacked more people. The attack on one of them, a man in his 40s, is classified as attempted murder.
