An explosion occurred during the night of Tuesday in a residential area in Storvreten in Botkyrka.
The police have bomb technicians on site during the morning and are investigating the incident as a public nuisance.
The police received an alarm at 02.30 that callers heard bangs so strong that windows and properties vibrated. On site, the police were able to establish that some form of detonation had taken place at a garage near a property.
– There is damage to this property and then to an adjacent property, so two different addresses have been damaged from one and the same blast, says Daniel Wikdahl, press spokesperson at the Stockholm Police.
No one has been found injured and there are currently no suspects for the crime, which is classified as public destruction.
