Catholic high school in Santa Ana, Calif., shuts down campus for the rest of the week after credible threat of violence

Threats of violence have prompted a Catholic high school in Santa Ana, Calif, to shut down the campus for the rest of the week

Mater Dei High School has closed its campus and canceled extracurricular activities through end of the week. 

Police say that a former employee has been making threatening and disturbing comments about other workers on campus, which led Orange County diocesan officials to shut down the campus for the rest of the week, reports CBS News. 

Police say that the threat was not directed at students, and they aren't investigating it as a criminal matter.

School officials said the high school will transition to an online education platform for the last week of classes and finals week. 

"We acknowledge the alarming nature of this message," the school said in a statement. 

More than 2,000 students attend Mater Dei.
