No one was injured, but the detonation caused material damage. The National Bomb Squad has been at the scene, which is now under investigation by forensic experts.
The National Bomb Squad will be there during the day and will try to find out what detonated it, says Leif Fransson.
At this time, there is no suspect and no information about who is the target of the explosion.
We are investigating who lives at the property and interviewing witnesses, in case anyone saw anything.
