The police have received several calls about at least one loud bang in Lindeborg in Malmö, according to the police who have confirmed material damage to a residential building with ground-floor apartments.
We suspect that it comes from an explosion, says the police's press spokesperson Patric Fors.
No one has been injured in the incident.
But there were people inside the apartment.
The alarm came in just after 6 pm.
No one has been arrested. The bomb squad is on its way to the scene.
