The fire is suspected to have been started and the police see a connection with the events on Sunday evening, when a large number of fires broke out.
However, the night until Tuesday has been clearly calmer, according to the police.
- It was a fairly normal call, but it is clear that we were a little extra attentive to the surroundings and stayed a little longer, says police spokesman Thomas Agnevik.
No one has been detained after the night's fire.
During the night, the police continued to strengthen surveillance in the city.
