A large detonation has taken place in Swedish city Borås on Saturday night, but police cannot find the origin of the explosion.
The explosion took place around half past eight, sending out a shockwave that set off shop alarms.
According to police, people have felt the shockwave and there has also been a smell of gunpowder in the air.
However police have not been able to identify the origin of the explosion. When police arrived on the scene they couldn’t find a place where the detonation took place.
“There is no doubt that a bang has taken place, but we don’t have anything more” said Morten Gunneng, officer in charge at police region west told SVT.
Police think that the device behind the explosion is a powerful banger. A banger is a very powerful illegal firework, which according to police can be compared to a hand grenade.
The most common type of banger used by criminals in Malmö contains 100 grams of gunpowder, which is enough to kill or seriously injure a person.
Last year saw a record number of 257 bomb attacks in Sweden, which is “unique for a country not at war”.
