We note that something has exploded, unclear what. There should be damages in the stairwell, but I don't know what kind of damages, says the police's press spokesperson Mats Eriksson to TT.
The residents have been evacuated from the building. No one has been injured.
The alarm came at 13.13 on Saturday. The incident is being investigated as general reckless destruction.
The national bomb squad will arrive soon, says Eriksson.
