TOKYO: Japanese police on Saturday arrested three North Korean crew members for suspected theft, a spokesman said, amid a fresh wave of North Korean ?ghost ship? fishing vessels washing up in Japanese waters. The three were among the 10 North Korean ?fishermen? spotted aboard a tiny wooden boat struggling in bad weather off the northern island of Hokkaido late last month. The 45-year-old captain and two other crew members, who all identified themselves as North Korean nationals, were arrested on suspicion of stealing a power generator, a Hokkaido Police Department spokesman said. The arrest came after some of them reportedly admitted to ?taking out? some electronic products from a remote Japanese island where they landed briefly to take refuge.
