The White House has returned to "normal operations" after a partial lockdown triggered when an individual threw a metal object over the fence, a US Secret Service spokesman said on Monday.
"An individual threw a metal object over the north fence line at the White House. Secret Service Uniformed Division officers immediately apprehended the individual without incident. All protective sweeps of the metal object were met with negative results," spokesman Shawn Holtzclaw said in an emailed statement.
