RIVERSIDE, Calif. — Threatening letters and an apparent homemade firebomb on campus led the University of California, Riverside, to cancel final exams and a graduation ceremony Friday, officials said.
Two handwritten, threatening letters were sent to the school that afternoon, campus Police Chief Mike Lane said.
School officials scrapped the ceremony after groundskeepers found two plastic bottles that contained what investigators think was flammable liquid near a burning palm tree at 5:25 a.m., Lane said.
Another suspicious device was found in a nearby planter three hours later, he said.
Spokeswoman Kim Lane said the university was working with police to ensure safety at five other graduation ceremonies planned for the weekend. The canceled ceremony would be rescheduled, she said.
