Bomb threat clears UPitt's Chevron Center

A bomb threat required the evacuation of the University of Pittsburgh's Chevron Science Center Monday evening, police said.

Shortly after 5 p.m. Monday, Pitt police received a phone call from an individual who found a note in a Chevron Hall women's restroom that stated a bomb would go off at 8:29 p.m. Pitt police evacuated the building by 6:15 p.m., according to Pitt spokesman John Fedele.

Pitt then sent in its canine unit, consisting of its lone police dog, named Officer Riggs, as well as two dogs from other police departments that are trained in locating explosives to perform a bomb search. The City of Pittsburgh's bomb and arson squads assisted. They found no bomb, and Pitt reopened the building at 9:30 p.m., Fedele said.

Pitt police have opened an investigation, Fedele said.

Fedele said that, before Monday, it had been "quite a few years" since Pitt's last bomb threat.

"Luckily, none of them have ever been more than scares," Fedele said.
