We received several calls about a loud bang and when we arrived at the scene, we could establish that something had exploded in connection with a door in an apartment building, says Torbjörn Lindqvist, duty officer at Police Region South.
No one was injured and the material damage was also limited.
It didn't amount to much more than a little soot on the door. But it must have been a pretty loud bang because I heard it all the way to the police station, says Torbjörn Lindqvist.
The alarm came in to the police just before 01. The area is cordoned off and will be investigated. No one is currently suspected.
The same door was subjected to a detonation on the night of February 17.
