An interesting success story from Norway (where they have many of the very same troubles we have here).
Basically, a white van was stolen in Norway and used by the thieves to drive around unnoticed and steal outboards.
A member of the public saw the van parked up beside a Polish truck and things being moved from one to the other.
Police arrived, questioned the men and searched the vehicles. In the snow chain compartment on the truck they found stolen outboards.
All the men were arrested and are awaiting trial. The police believe the engines were stolen to sell on when back in Poland.
