Diablo Valley College officials are adding a stronger police presence Thursday as a precaution following an anonymous threat discovered in the form of graffiti on the Pleasant Hill Campus Wednesday afternoon.
The graffiti was seen in the men’s restrooms in the humanities building and in the library, police said.
"Counselors will be available this week and next to help students who are experiencing increased anxiety," the school said in an advisory to students.
College officials said classes and services will run as scheduled but additional police officers and counselors will be on campus.
