A couple of hours later, a police patrol stopped and checked, making some discoveries in the car that could possibly be linked to the fires. Three people have been interviewed and a preliminary investigation into the arson fire has begun.

- Some bargains were made in the car that showed that you were out to light things up. After the hearings, you will have contact with prosecutors to see if they are to be arrested, says police spokesman Torbjörn Lindqvist.

Not the first time this week that the business owner is affected.

- Apparently, the owner should be exposed to some kind of fire attack this week, but then against his own home, says Torbjörn Lindqvist.

No one should have been injured.
