The alarm came in at SOS Alarm at 19.19 and according to the caller there must have been a lot of smoke and smell of fire at the scene.
- We have a patrol there who is trying to get a grip on the situation and block the area, says police spokesman Kenneth Johannesson.
Emergency services and police were alerted to the scene.
- It has been a big bang and smoky in the stairwell. We have vented the smoke and found no fire. As far as I know, no person should have been injured in the incident, says Stefan Fröbom, internal commander at the Rescue Service Dala Mitt.
The police have launched a preliminary investigation into the destruction of the property.
- We document and record testimony. A technical examination will be carried out, if it is then done by the national bomb protection or by regional techniques remains to be seen.
