Rescue services, police and ambulance were alerted to a loud bang just after 23.30 and are now working on the scene. Something has exploded outside an outer door to a row house, where several people are said to have been.
As I understand it, there have been adults at home, says Carina Skagerlind.
No one is physically injured, but there should have been minor damage to a house facade.
The pictures I've seen show no major damage. As I understand it, there is some electrical cabinet nearby that has been damaged and there has been minor damage to the house facade.
The area is now cordoned off and the police are looking for suspects, including with a dog patrol.
So far, no one has been detained, but we are continuing to go door-to-door and looking for any individuals who may have been out and about and can be suspected in this matter, says Skagerlind.
The National Bomb Protection will investigate what has exploded. A preliminary investigation into reckless endangerment and offenses against the law on flammable and explosive goods has been initiated.
