An airline official says a Southwest Airlines flight headed for Baltimore was diverted to Nashville after what he described as "suspicious behavior" by a passenger.

The flight originated in Albuquerque on Saturday morning and landed in Nashville at about 1:10 p.m. CDT.

Southwest Airlines spokesman Chris Mainz told The Associated Press that the passenger's behavior on the plane wasn't disruptive, but he declined to elaborate.

Nashville International Airport spokeswoman Emily Richard told the AP no arrests were made.

Mainz said police ordered all the passengers off the plane, sent them back through security and examined the plane before passengers were allowed back on. It took off again about 3:55 p.m. CDT.

Mainz could not say whether the passenger in question was allowed back on the flight.
