In a news release, Superintendent Dr. Antonio Shelton said vandals caused tens of thousands of dollars in damage at Malibu High School overnight Tuesday. The vandalism was done by a group of 40 or more current seniors and former students between the hours of 11 p.m. and 2 a.m., the release alleges.

A long-running ritual drew a harsh response this year after damage piled up and school officials called in the sheriff.
