The explosion occurred in Norsborg on Saturday night. After questioning, the suspected perpetrator has been detained. However, the police do not want to go into details about the arrest at present.
It happened a little later and it was not adjacent to the crime scene. We had an offensive investigative work and help from witnesses who had made certain observations, says the police's press spokesperson Ola Österling.
A mapping of the suspect is currently underway.
No personal injuries have been reported, but there was one or more persons in the apartment at the time of the incident. The police do not want to specify exactly how many. The damage to the apartment is limited, according to the police.
The explosive charge was directed at a specific apartment door and the apartment door has been damaged. We are working on gathering intelligence and mapping to get answers to why, says Ola Österling.
The technical investigation of the crime scene is complete, and according to the police, a large number of supplementary interviews are expected during the day.
The police have gone door-to-door and also questioned a person who was in the apartment.
The incident is being investigated as reckless endangerment and a violation of the law on flammable and explosive goods.
