By drilling through a wall from outside, the thieves could access the key cabinet where the car keys were stored. The alarm went off at 03.59 and security guards were in place just over five minutes later, but then both the thieves and the four luxury cars were away from the car company in Strängnäs.

A car found

On Monday morning, one of the cars was found thanks to tips.

"It was found in Nykvarn," says Jeanette Björk, preliminary investigator at Strängnäspolis police, who does not want to go into further details.

She also does not want to go into whether the surveillance pictures gave anything, or what they got out of the thieves' car which they seized at the car company.
