The alarm was received at 01.15 on Tuesday night.
The owner of the car wreck had begun to protect nearby cars by steering the burning cars together with a tractor.
When the rescue service arrived at the scene, they helped to soak and extinguish the fire.
Flared up again
At 04.40 one of the cars had started to burn again and the rescue service went back and extinguished the burning car.
It is unclear why the fire started.
According to initial information from the rescue chief on standby, the site had remained untouched before.
- It is strange that it has started to burn like that, says Kenneth Paldanius.
Police will visit the scene on Tuesday.
