PITTSBURGH (AP) - Dozens of bomb threats at the University of Pittsburgh over the past two months have students on edge and show no sign of stopping soon.
On Monday, four threats had been made by mid-afternoon. The school has set up security checkpoints at building entrances and even offered a $50,000 reward for information leading to an arrest.
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 has urged faculty to make arrangements for students to make up classes or exams missed because of the evacuations, but the school says there are no plans to end the semester early.
No bombs have been found. A task force made up of campus police and the FBI is investigating.
