U.S. transportation officials report another incident on a flight into the U.S. city of Detroit, Michigan, two days after a Nigerian man was arrested for trying to blow up an airplane on the same route.
Officials say the pilot of the Northwest Airlines flight from Amsterdam Sunday notified authorities about a disruptive passenger and requested emergency help on landing.
The plane landed safely and there were no reports of injuries. Sources say the plane's crew became alarmed because a passenger had locked himself in the bathroom for a long time.
An airline spokesperson says a man was arrested when the plane landed.
President Barack Obama issued a statement from his vacation in Hawaii Sunday, saying he had been notified of the new incident and stressing the importance of heightened security measures for air travel.
The flight, number 253 from Amsterdam, is the same one on which a Nigerian man was arrested Friday for trying to set off an explosive. Airport authorities in Europe and the United States have tightened security measures since the Christmas Day incident.
