Just hours after Monday’s shooting rampage at the Washington Navy Yard, a man threw some firecrackers over the fence at the White House.
Witnesses say they sounded like gunshots.
Uniformed Secret Service officers tackled the man within seconds, handcuffed him and arrested him.
The White House was locked down as a precaution. It was reopened an hour later.
Police identified the man as Alexander Sahaghan; charges are pending.
