Russell OB Date: 2/8/06 Photographer: Linda Davidson / staff / twp Location: Russell Office Bldg, Washington, DC Caption: Capitol police and Hazard Material teams descend on the Russell Office building on Capitol Hill after a sensor in the attic of the building went off. Tests currently are being performed. They suspect right now it may have been something as simple as cleaning chemicals that set the sensor off.
