A Nigerian man has been arrested after barricading himself in a toilet aboard a plane with the same flight number as the one attacked on Christmas Day.
The 30-year-old is reported to have boarded in Lagos with no luggage.
Airline crew said on the Amsterdam to Detroit leg of Northwest Airlines flight 253 he became verbally disruptive.
Two people told Fox news the man then locked himself in the toilet for over an hour.
On touchdown the man was arrested by FBI agents who were waiting on the runway.
All 257 passengers and 11 crew left the plane safely.
It follows an incident on the same flight number two days ago in which Nigerian Umar Farouk Abdul Mutallab was arrested for trying to light an incendiary device.
Links between Mutallab and al Qaeda are being investigated.
