MINNEAPOLIS — A Delta Air Lines flight headed for Minneapolis returned to Japan because of some disruptive passengers.

Delta says the Boeing 747 was three hours into a 13-hour flight Monday when the decision was made to turn back to Japan, where the passengers were removed by Japanese authorities.

Delta spokeswoman Susan Elliott did not have details on the nature of the disruption, but the Asahi newspaper in Japan says two male passengers locked themselves in the restrooms for about an hour and refused to come out. Narita International Airport officials say the men were questioned at the immigration office, but apparently were not arrested.

Airport officials say the flight took off Tuesday after spending the night.
