Something has detonated by a gate to an apartment building in Håkanstorp in Malmö, according to the police.
The police do not believe it is about explosives, but the bang caused a smaller fire. There is no information that anyone should have been injured.
Right now we are carrying out routine investigative measures, technical investigation and so on, said Henrik Hagström, duty officer at the police, earlier during the night.
The police's bomb technicians have not been called in. The alarm came just after 00.30 on the night to Sunday.
