It was at 01.30 during the night until Thursday that police were alerted to Volvo's parking in Torslanda. A car had exploded.

"There are no personal injuries but only material damage," said Johan Ljung, the police officer in charge, shortly after the alarm.

Since then, extensive investigative work has been going on for the Gothenburg Police, which has had a lot of surveillance film to analyze.

"We see very clearly that there is a car there and a charge is placed on this particular car and it is blown up and the car leaves," says Ben Wallin, preliminary investigator at the police in the West region.

No clear threat picture emerged

They are now working to try to identify the vehicles and people who appear in the camera pictures. But these are dark pictures. It also awaits more hearings, not least with the person who owns the blasted car - a worker at Volvo.

- Of course, it is from the person's story that we can move on, says Ben Wallin.

Based on that story, does there seem to be a threat to this person?

- No, but that's what we assume. Because there is nothing that has been thrown during a bunch of cars, but it is clear that it is precisely this car you have chosen.

Ben Wallin goes on to say that the blasting device used was a coarser variant of the banger type.

- There are different sizes of them. Here it has blown away parts of the engine heads, so it's not like a firework piece. There is really pressure in them, he says.

Worries among employees

The incident has caused concern among workers at Volvo. When SVT News West comes to the site on Thursday, several employees have gathered at the site.

"What's going on, dare you go to work," one woman asks.

Ben Wallin has also understood the difficulties for the Volvo employees.

- We have been out there talking to their workers as well, and of course there will be unrest in the ranks when this happens, he says.

- But it does not appear to be completely random, but you have chosen this particular car. Then whatever happens, it will have to prove the future.
