UC Davis police ordered the evacuation of Mrak Hall, the campus’s main administration building, after someone reported finding a suspicious device inside Tuesday afternoon.
The 3:40 p.m. discovery prompted authorities to summon the Yolo County Bomb Squad to the scene and issue a campus warning advising people in neighboring buildings to shelter in place.
Following an investigation, the object was determined not to be a threat, and Mrak Hall was reopened at about 5:20 p.m.
