Small Drone Crashes At White House

According to Secret Service, a small drone landed in a tree at 3 a.m. ET Monday. The WH went into lockdown. 

WASHINGTON (AP)  -- A small drone flying at low altitude crashed into the White House complex before dawn Monday, the Secret Service said. President Barack Obama was not at home and the White House said it did not pose a security threat.

The crash prompted an immediate lockdown of the White House grounds until officials could examine the drone. The Secret Service said the 2-foot-long device was a quadcopter — a small, unmanned aircraft that is lifted by four propellers.

"An investigation is underway to determine the origin of this commercially available device, motive, and to identify suspects," said Secret Service spokesman Brian Leary. He said the drone crashed on the southeast side of the White House complex just after 3 a.m.
