Extensive graffiti, broken windows, fire extinguisher discharge and toppled furniture at Warner Springs High School prompted district officials to cancel class for cleanup, San Diego Sheriff's Officials (SDSO) said.
A school maintenance worker arrived Tuesday morning to find the extensive vandalism in multiple classrooms at the school on State Route 79, far east of Escondido, authorities said.
Warner Springs Sheriff's deputies responded at 5:13 a.m. Several buildings, classrooms and officers were found damaged.
The damage was severe enough to cancel school for at least Tuesday, deputies said. Officials began cleaning up and repairing the vandalism.
The closure covered the entire school district complex, including kindergarten through 12th grade.
The repairs will cost several thousand dollars, SDSO said.
The School Resource Deputy is responding.
No other information was immediately available.
Anyone with information is asked to call Crime Stoppers at (888) 580-8477 with information to remain anonymous.
