KANSAS CITY, Mo. (AP) — Authorities say they didn't find anything suspicious on an American Airlines plane that was searched after landing at Kansas City International Airport.

FBI spokeswoman Bridget Patton said Friday that someone at Chicago's O'Hare Airport who missed Thursday night's flight said something that could "possibly be perceived as a threat." She says the plane was searched after landing as a precaution.

The Republic Airlines flight operated for American Eagle was directed to a remote area of the airport where its 63 passengers and four crew members disembarked before the plane and luggage were searched.

Chicago police spokesman Officer Mike Sullivan said no arrests had been made as Friday morning.
