United Airlines says one of its flight attendants intentionally deployed the emergency evacuation slide on an airplane after it had landed at Houston’s Bush Intercontinental Airport.

The attendant then slid down and walked away, Houston’s KPRC2 reports.

United spokesman Charlie Hobart says officials are still investigating why the flight attendant, whose name was not released, deployed the slide from one of the plane’s doors after the flight from Sacramento, California, had landed late Monday morning.

Hobart says the flight attendant has been removed from her flying duties and that the individual’s 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 was inspected.
