The alarm came in just before 4pm on Monday afternoon at the Scania area in Oskarshamn.
The truck then, for unknown reasons, drove straight through the wall of an industrial building in the area.
– It’s a pretty big hole, says Tony Bergelind.
No one inside the building is said to have been injured, but the truck driver has been taken to hospital with unclear injuries.
Initially, there was some risk of collapse in the building, but shortly after 5 p.m. the building was secured and the emergency services finished their work at the site.
