The Alfredo restaurant in central Örebro caught fire in the early hours of Monday morning, with one person taken to the local hospital with serious injuries.
“The fire is extinguished and the area has been cordoned off. We are still unsure of what caused this,” said Per-Anders Olserud of the Örebro police to the Aftonbladet newspaper.
While the fire was put out before the emergency services arrived, police are refusing to speculate on whether the loud noise heard beforehand by bystanders and nearby residents was indeed an explosion.
“I cannot confirm nor deny that there was an explosion. A number of alarms went off inside the mall and we believe it may have been some kind of a bang triggered them. We have also heard the same story from the people living above the shopping mall,” Olserud told the paper.
A police investigation has been launched, and forensic technicians have been on the scene.
