White House Briefly On Lockdown After Drone Incident

The White House was on lockdown Thursday afternoon and traffic was shut down after someone tried to fly an unmanned aircraft near the grounds, according to multiple sources.

A senior official told ABC the Secret Service detained a man in connection with flying a drone in Lafayette Square near the White House. The aircraft reportedly never crossed the north fence of the White House.

This is the second drone incident at the White House this year. In January a Defense Department employee crashed a drone into the White House lawn.

NBC tweeted this photo Thursday afternoon, saying a "small drone" was flying around 100 feet.
