According to the on duty fire chief, the fire did not pose any danger to people nor was it expected to spread to nearby buildings.
However, the rescue department urged people to stay inside and close their doors and windows against the toxic smoke.
The fire department received the fire alarm a little before 2:30am Monday morning.
A dozen rescue units arrived at the scene. Putting out the fire and clearance work lasted several hours.
The shopping center on Keskustie was built in the 1960s. The space, which was just over a thou-sand square meters, was under renovation and therefore unoccupied. There is no information about the cause of the fire.
