Pitt sent out an Emergency Notification Service alert for a bomb threat in Chevron Science Center just after 5 p.m., urging everyone to evacuate the building.

Emergency responders and the city’s bomb squad are currently at Chevron Science Center and searching the building with K-9 units. The building, on Pitt’s upper campus, is on the 200 block of Parkman Street in Oakland.

Pitt spokesman John Fedele said that the University sent out the alert after a Pitt employee found a message in a Chevron Hall bathroom that stated a bomb would go off in the building at 8:30 p.m.
