Second Nigerian taken into custody

A Nigerian passenger on Sunday's booking of Northwest Airlines flight 253, from Amsterdam to Detroit, has been taken into custody at the destination city's airport.

This is the same route from which a suspect was taken into custody after reportedly trying to light an incen-di-ary device two days earlier.

Airlines authorities are confirming that a Nigerian man locked himself in the airplane's lavatory for one hour, and became verbally disruptive. In response to the incident, crew members requested emergency assistance upon arrival.

They asked for security personnel to physically remove the individual after the aircraft landed. The other 255 passengers all went out of the cabin safely. The FBI has given an "all clear" after investigating what the agency says was a "non-serious" incident.
