Man arrested in front of White House

The Secret Service has arrested a man for tossing firecrackers over a fence at the White House.

A federal law enforcement official says the shoeless man was immediately arrested.

An Associated Press photographer heard what sounded like two gunshots outside the White House.

Three uniformed Secret Service officers arrested a middle-aged man.

The man was white, with dark hair, a blue shirt and white shorts. His white shoes lay on the ground near where the officer tackled him.

The incident happened just hours after at least one suspect opened fire inside the Washington Navy Yard, killing at least 13 people. The gunman was also killed.
