Bomb threats unnerve campus

PITTSBURGH – 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 about 4 a.m.

Under new security measures, students and faculty will need a school ID to get into buildings. Nonresidents won’t be permitted in dormitories, and a $50,000 reward is being offered for information.

The threats have caused some professors to move classes outdoors or offer them online and have led some students to stay off campus. The university, located a few miles from downtown Pittsburgh, has about 3,800 full-time faculty members who serve 34,000 students.

No bombs have been found and nobody has been injured. There have been a total of about 25 threats.
