An unattended bag found in the stairwell of the Oregon State Senate forced an evacuation of the building and cancellation of Senate work Tuesday. 

State Police Lt. Terrie Davie says just before 10 a.m., OSP Capitol Mall Troopers were notified that an employee found a suspicious object in a stairwell near the Senate gallery.

The owner was not immediately found, so OSP coordinated an evacuation of area offices. 

Hazardous device technicians responded,  x-rayed the contents and found it contained camera equipment. 

Workers returned to their offices by 11 a.m. and the camera equipment was returned to its owner after contact with the OSP.
