United Airlines says a flight attendant deliberately deployed the emergency evacuation slide after a flight from Sacramento, California, landed at Houston's Bush Intercontinental Airport.

United spokesman Charlie Hobart says officials are investigating why the female employee, whose name has not been released, deployed the slide and jumped onto it to exit the aircraft Monday morning.

Hobart says the flight attendant has been removed from her flying duties and that her actions do not represent the more than 20,000 flight attendants who work for the airline.

No one was hurt during the incident and Hobart says the plane was put back into service after a new slide was installed and the aircraft inspected.
