"It was the guards who responded to the boat and contacted the police," says Daniel Wikdahl, press spokesman at the Central Police Region.

On board the boat, the police found suspected theft.

- I can't go into what it was, but you can say big and small, says Daniel Wikdahl.

Several people were on board the boat when police investigated it. One person departed from the site. One person could arrest the police for suspected receiving. Another man who was aboard the boat turned out to be wanted.

- He would serve a sentence, so he is now in custody and will probably be handed over to the prison, says Daniel Wikdahl.
