CHICAGO (AP) – Lufthansa said a flight from Los Angeles to Frankfurt, Germany, made an unscheduled landing at Chicago’s O’Hare International Airport after a passenger’s laptop caught fire.

The airline said Monday night’s landing at O’Hare was a precautionary step after an overheated laptop caused a small fire in the passenger cabin.

WLS-TV reported the fire was out by the time the plane made a safe landing.

None of the passengers were injured, but Lufthansa said in a statement that two flight attendants were treated for smoke inhalation.

The airline said its ground staff was helping passengers get rebooked for flights to their final destinations.
