On Friday morning police were called to a rest-stop on a northbound lane on the E4 motorway between the southern Swedish towns of Linköping and Norrköping to investigate a rather unusual robbery.

The night before robbers had broken into a foreign lorry and made off with the contents, which was mostly dog food, the news website Corren reported. 

“I guess the driver was asleep and only discovered in the morning that the cover had been cut and the goods stolen,” police spokesperson Thomas Agnevik told The Local.

Agnevik doubted that the thieves actually intended to steal dog food.

“It’s probably a mistake from the thieves’ side,” he said. “Usually they tend to steal electronic goods, cigarettes or alcohol. I've seen stranger things, but this was a bit special.”

The extent of the theft is currently unclear and at present police have few leads to sniff out the perpetrators.

Police are keen to hear from any witnesses in the area.
