WASHINGTON - A suspicious van is forcing the evacuation of about 1,000 people at a building on Capitol Hill. The vehicle is reported to be in the 100 block of First Street, NW. The Associated Press reports an unidentified man who claimed to have a suspicious device in his car has been taken into custody. Brian Doyle, a spokesman for the Department of Homeland Security, said hazardous materials teams had been dispatched to the site. The evacuation is occurring at 101 Constitution Ave., NW. in a building that houses various private sector companies. WTOP's Capitol Hill Correspondent Dave McConnell who is near the scene says everybody is leaving calmly the building. Two sources tell CNN that a man in a van is claiming to have a bomb. The U.S. Capitol is not involved in the evacuation.
Acording to a Captiol Police alert sent to Senate staff, several streets are closed in the area, including Delaware and Constitution Avenue (Southbound); 3rd Street and Constitution Avenue, NE (Westbound); Louisiana and Constitution Avenue, NW (Eastbound).
