Security tighter at Diablo Valley College after violent threat scrawled on campus

PLEASANT HILL, Calif. (KTVU) - Security is tight on the Diablo Valley College campus on Thursday after a threat was found on a bathroom wall.

Students received an alert Wednesday night from the Contra Costa College District, saying that threats were scrawled in graffiti on the wall of two bathrooms – one in the library and the other in the Humanities building of the campus in Pleasant Hill.

One of the messages, which KTVU is not showing, was written on the sidewalk and references "imbecile students," who if they were reading the words were "lucky to be alive." The message was signed by Z. and had a picture of a gun next to it. 

School officials are asking students to remain vigilant and be aware of their surroundings. The campus is open but there will be counselors on hand for students who might be experiencing anxiety or stress over this incident. There was a similar threat made last March before midterms and school officials shut down the campus then.

Grace Hull wasn't worried at all.

"I think it's ridiculous," she said. "It's just somebody not studying. That is literally what it is. Nobody is going to come and do something to the school. We're fine."
