A British governmental body is leading the investigation into a fire aboard an empty Dreamliner aircraft at Heathrow Airport, an incident that has sparked renewed concern about Boeing's newest plane.

The Air Accidents Investigation Branch, part of the Department of Transport, says the Ethiopian Airlines 787 plane was moved to a secure hangar at Heathrow early Saturday so that the investigative team can try to find out what caused Friday's fire.

It did not cause any injuries because no one was aboard the plane, but the fire forced runways at Heathrow to shut down for nearly an hour as emergency crews attended.

Others also involved in the investigation include the U.S. National Transportation Safety Board and the Federal Aviation Administration, Boeing, and Ethiopian Airlines.
