A smaller explosion has occurred in Årstaberg in southern Stockholm.
It seems like there has been some form of detonation, says the police's press spokesperson Anna Westberg.
The alarm about the incident came at 16.45 on Tuesday.
It is a pane in a door to an apartment building that has been shattered, but there are no major damages to the door, according to the police.
Since the national bomb squad has investigated the site, it can be established that the glass was shattered by a smaller detonation.
The incident is classified as attempted general destruction.
The police have taken some people in for questioning, but there is no information about anyone being arrested.
