It is the latest of a growing number of attacks in Sweden, with a man being killed by a grenade that he picked off the ground only two weeks ago.
Police spokeswoman Anna Goransson was quoted as saying by Aftonbladet: ”“The place is locked off and the bombing group is on its way,”
The alleged attack happened shortly after 9pm local time in the courtyard of the police station. “Fortunately, no people have been injured, but cars, I cannot say how many, have been damaged,” Goransson told reporters.
Authorities have yet to confirm what caused the explosion, but local media are reporting that a hand grenade was used.
