White House returns to normal operations after lockdown

WASHINGTON (AP) — The Secret Service says the White House has returned to normal operations after being placed on lockdown early Monday afternoon.
Secret Service spokesman Robert Hoback says someone at about 12:15 p.m. threw a metal object over the north fence along Pennsylvania Avenue and was arrested without incident. Hoback did not identify the person, though a witness saw a woman placed in handcuffs.
Fire trucks and a hazardous materials response unit were called to the scene. It&
