An apartment building was badly damaged after the explosion, which the police had to evacuate due to the risk of landslides.
In Sweden, many received calls from people who heard a loud bang near an apartment building in Solna municipality, late Thursday evening. The police confirm the opposite SVT That an explosion occurred.
Daniel Wekdahl of Stockholm Police told VG that no injuries have been found so far.
– But the search is still going on, he said at 23.55.
– We have evacuated people at the stairwell, and we are constantly evaluating whether we should evacuate nearby stairs.
Later Friday night, Expressen wrote that the stairwell had been so badly damaged that it was in danger of collapsing.

We don’t know what happened, but we suspect something criminal.
