The flight was diverted to Atlanta after a passenger was seen with a box cutter.

A passenger was taken into custody by the Atlanta police after the plane made a safe landing at the Atlanta airport.

The passengers are being provided hotel accommodations in Atlanta after deplaning the plane. There will be a new flight that will take passengers from Atlanta to their final destination.

Tim Turner, a spokesman for the Atlanta airport, said that a passenger had been threatening to stab passengers and crew on the plane. The box cutter was found on the man after he was arrested.

The officials at the Cincinnati/ Northern Kentucky International Airport could not be reached. The Atlanta Police Department's messages were not immediately returned.

The man was able to get a box cutter onto the plane. The transportation security administration has authority over security and passenger screening at U.S. airports.

After the 9/11 terrorist attacks, box cutters were not allowed on airplanes.
