FBI probes FIFTY-SIX bomb threats at University of Pittsburgh

Dozens of bomb threats at the University of Pittsburgh, including at least twelve on Monday, have prompted professors to start holding classes outside and forced security officials to put in new building access measures and offer a $50,000 reward for information.

There have been 56 threats since they began in mid-February, at first targeting a landmark building at the center of campus.
