ESCONDIDO, Calif. (AP) -- A threat of violence has led four Escondido charter schools to shut their doors for a day as a precaution.
U-T San Diego reports (http://bit.ly/1cyMfek ) that Heritage K-8 Charter School, Escondido Charter High School, Heritage Digital Academy Middle School and Heritage Digital Academy High School will be closed Friday.
Notices were posted late Thursday on each of the schools' websites. The notices say classes will resume Tuesday. Monday is Martin Luther King Jr. Day.
Escondido police Sgt. Scott Walters told the newspaper that a “specific threat” against a campus was written Thursday on a social networking site.
He says police are “treating it as a credible threat.”
No details of the threat have been released, and no arrests have been made. Walters says school officials decided to close the facilities.
