The fire started in a garage and then spread to a townhouse.
The fire broke out in a car, and both the police and emergency services arrived at the scene. The fire initially spread to the townhouse next door, but no one was injured. People have evacuated on their own, says Per Fahlström, press spokesman for the police.
Twelve to fifteen cars and one of the apartments were destroyed in the fire. Several apartments are also reported to have smoke damage, according to the fire service.
A preliminary investigation has been opened on suspicion of arson. One person has been arrested.
The fire department had almost extinguished the fire by 4 a.m. The area has been cordoned off for the police's technical investigation.
