Appliances, a solar panel and other items have gone missing from a hut on the same uninhabited islet off Hokkaido where 10 North Korean seamen purportedly took refuge from bad weather before requiring a maritime rescue from the Japan Coast Guard, officials and sources familiar with the matter said Monday.

Police and coast guard officials searched the islet on Sunday. According to the sources, a TV, motorbike, refrigerator, rice cooker and power generator were found missing from the ransacked hut, which had been locked.

A wooden fishing boat with 10 North Korean men on board was found adrift near the islet last Wednesday. The fishermen, who were rescued by the Japan Coast Guard, were seen dumping appliances into the sea from their boat.
