A Pitt ENS alert sent just after 10 a.m. Thursday advised everyone to evacuate the Cathedral of Learning, Posvar Hall, the Chevron Science Center and the Frick Fine Arts Auditorium. These threats bring the total for the semester to 23, and the total for the week to 16.

The four threats were cleared by 12:20 p.m. However, access to the Chevron Science Center is restricted. People must enter through the University Drive entrance and show Pitt identification when entering the building

Pitt police Chief Tim Delaney said Wednesday if the person or people responsible for the threats is doing so because they have a message or an issue, he would be there to help them resolve their issue.

“I want to see if the individual doing this will contact me,” Delaney said. “It may be a student, it may not be a student. Whoever it is, give me a call.”

Pitt has offered a $50,000 reward for information that leads to the perpetrator(s) of the string of threats.
