Around midnight on Friday night, the police were alerted to an explosion in a residential area.
"It is a case involving an explosion that we are currently working on. There are no injuries or material damage," Johan Josarp, a police duty officer, tells the newspaper.
A person has been arrested on suspicion of molestation and violations of the Act on Flammable and Explosive Goods.
"It seems to be some kind of conflict and has nothing to do with gang crime or the like," says Johan Josarp.
