RIVERSIDE, CA (AP) - A former U.C. Riverside student has been arrested in connection with a homemade firebomb and threatening letters found on campus that forced the postponement of exams and a graduation ceremony.
22-year-old Audley Yung of Richmond was arrested at around 2 p.m. Saturday on suspicion of possession of a destructive device, arson, and making terrorist threats.
Final exams and the graduation ceremony for the school of business administration were scrapped Friday after groundskeepers found two plastic bottles that possibly contained flammable liquid near a burning palm tree on campus.
Another suspicious device was found hidden in a planter near that building three hours later, and two threatening letters were received in the afternoon.
Police said Yung attended UC Riverside in 2002 and 2003, and took summer session classes as recently as 2006.
Five more graduation ceremonies, including one for about 600 students the College of Humanities, Arts and Social Sciences, were held under tight security Saturday -- but went smoothly.
The business school graduation was rescheduled for Monday morning.
