It is about some form of detonation in an apartment building. Both the entrance and an adjacent bicycle storage have been damaged, says Sanna Lagerqvist, duty officer at the police.
There was initially heavy smoke in the stairwell and we have had a dialogue with the rescue service about possible evacuation of residents. But it has not been initiated yet.
Neither the police nor the rescue service have information on how close to the explosion the injured person was.
No person was arrested for the incident at 05.00. The bomb squad is working on the site.
We are trying to hold interrogations right now and we have an ongoing investigation, says Sanna Lagerqvist.
The alarm about the explosion came in at 03.20 during the night towards Saturday.
