WASHINGTON (Reuters) - A huge U.S. House of Representatives office building was closed for five hours on Friday in a security alert, but after a floor-by-floor search police said possible gunshot sounds had apparently turned out to be noise from construction work.
The Rayburn building was sealed for five hours because of a report to police of the sound of gunfire in the building garage. U.S. Capitol Police said when they reopened the building they had found no sign of criminal activity and the sounds were apparently made not by gunfire.
