We have obtained an understanding of which persons live at the current address and what other activities are there, and it forms the basis for our assessment that this has taken place in the wrong location, says the police's press spokesperson Daniel Wikdahl and adds:
There is no reason at all for such a thing to happen where it has happened.
No one was injured in the blast, but a number of windows were smashed.
A preliminary investigation has been initiated regarding public endangerment. No one is detained in the case.
