Something has exploded in connection to a restaurant entrance, says Torbjörn Lindqvist, duty officer at the police, to TT.
The alarm came in just after 3 am, on Tuesday morning. No one was in the building at the time.
What I've been told is that it's about smashed windows, says Lindqvist and continues:
The restaurant is located in an industrial area, or equivalent. So there are no residential buildings nearby that are affected.
One person has been arrested on suspicion of general destruction, reports P4 Sörmland.
A larger area has been cordoned off and the national bomb squad is on its way.
