Diablo Valley College in Pleasant Hill was closed Thursday after receiving a “potentially serious threat” against the campus, Timothy Leong, public information officer, said.
Leong said the closure was taken as a precaution, and all classes and college activities at the college were canceled for the day.
“The college found graffiti threatening the use of a firearm on the DVC-Pleasant Hill Campus,” Leong said in the school’s announcement. “The situation is under investigation, and so we are unable to share any further details at this time.”
He declined to elaborate further about the nature of the threat.
The college notified its staff and students of the closure. Classes and activities at Diablo Valley College-San Ramon campus, Contra Costa College and Los Medanos College remained open Thursday.
“The safety of our students, faculty and staff is our top priority, Leong said.
