A drone aircraft crashed onto the White House lawn overnight while the President was out of the country.

Secret Service spokesman Brian Leary told reporters the device was a quadcopter about two week in diameter.  The unmanned aircraft was flying at a low altitude before crashing on the southeast side of the executive mansion around 3:08 a.m. Monday.

“There is a device that has been recovered by the Secret Service at the White House,” White House spokesman Josh Earnest said when asked if a drone was found. “The early indications are that it does not pose any sort of ongoing threat to anybody at the White House.”

While the President and First Lady were in India, the President’s children were inside the White House because they had to stay behind to attend school.

The White House was darkened and the grounds placed on lockdown for around two hours while the Secret Service conducted their investigation.  The Secret Service would not say if there were cameras on the device that were transmitting to a remote location.

The incident is the latest in a round of security breaches at the White House over the past year.  Former director Julia Pierson was forced to resign last year after a Texas man with a knife was able to get inside the White House.
