White House Lockdown Lifted After Drone Spotted Flying Nearby

The White House was briefly placed on lockdown this afternoon after a man allegedly tried to fly a drone near the building, authorities said.

The Secret Service has detained and is questioning an individual in connection with a drone flying in Lafayette Park, according to a senior official.

The drone never crossed the north fence line of the White House, officials added.

Traffic was shutdown on Pennsylvania Avenue due to what the White House would only call a "security situation."

The person who has been detained has not been identified.
