There were a lot of people at the scene and the police had to help keep the unauthorized at a distance.
- It must have been a bit chaotic.
It will be easy in case of fires and other accidents for that matter.
There are many curious people who want to come and look and this was an apartment building so there were a lot of people in the area, says Björn Öberg who is a press spokesperson at the police.
The police have started an investigation
The fire was quickly extinguished and the police have now cordoned off the place.
Technicians have arrived to conduct a crime scene investigation.
- We are investigating it as a serious arson.
You have to have a heading to be able to block off and be able to make an investigation, and that there was a serious arson is due to the risk of spreading and personal injuries, says Björn Öberg.
The condition of the woman who was taken to hospital is unclear.
