ANCHORAGE, Alaska, June 14 (Reuters) - A Northwest Airlines (NWAC) jet bound for Tokyo made an unscheduled stop in Anchorage to drop off a passenger who smoked in the restrooms, threatened a flight attendant and tried to kiss some of his fellow-passengers, the Federal Bureau of Investigation said Friday. William E. Mullis, 47, of Savannah, Georgia, was arrested on Thursday after his plane landed in Anchorage, the FBI said. He was being held in a local jail and is scheduled for a court hearing on Monday, where he will be charged with interfering with an airline crew, said FBI Special Agent Robert Burnham. According to flight crew members, Mullis began behaving erratically soon after the plane left Detroit, and he was intimidating the other passengers, the FBI said. ©2002 Reuters Limited.
