The man was stopped by store staff and a security guard. When the police then searched the man, it turned out that he had pressed down the chocolate cakes in a swimsuit that he wore under his regular clothes.
Since the theft is considered "systematic in approach", the crime is considered serious, the police write.
The price of chocolate products has increased by over 20 percent compared to last year, according to the comparison service Matpriskollen. In May, it was reported from Denmark that one of the country's food giants introduced theft alarms on the chocolate cakes.
