Dozens of bomb threats at the University of Pittsburgh, including at least four on Monday, have prompted professors to start holding classes outside and forced security officials to implement new building access measures and offer a $50,000 reward
The threats began in mid-February, at first targeting a landmark building at the center of campus. But in recent weeks numerous buildings have been threatened. Four threats had been made by mid-afternoon Monday, starting at about 4 a.m.
"It wasn't really until probably a few days ago that this started to affect me, as far as my feelings of security," said Dawn Diehl, who's studying for a master's degree in library science. "So now it's pretty alarming. We've never had an experience like this. I kind of have that feeling like, where's this going to end?"
Diehl was surprised Monday to find all but one door to the main library locked and everyone's bags being searched.
