Police in Washington gave the all-clear signal Friday afternoon after investigating reports of a vehicle containing a possible explosive device parked a few blocks from the U.S. Capitol.
Police and security personnel sealed off streets near the vehicle, about one city block from VOA's Washington headquarters.
Bomb squad robots were used to investigate the vehicle. Police could be seen taking an industrial-size drum out of the vehicle.
They found nothing suspicious.
The investigation caused traffic tie-ups in the area near the Capitol, just a few blocks from where the dedication of the new National Museum of African American History and Culture is to take place Saturday morning.
