Anonymous cell phone threat prompted Los Osos Middle School lockdown

Los Osos Middle School was placed on lockdown Wednesday afternoon after an employee received an anonymous threat on their cell phone.

San Luis Obispo County Sheriff’s Office spokesperson Tony Cipolla said the school received a “generalized threat” and called in deputies to respond. Because it was the end of the school day, students were being released to their parents while the law enforcement presence was on campus, he added.

San Luis Coastal Unified School District Superintendent Eric Prater told The Tribune the lockdown was prompted when a staff member received an anonymous threat on their personal cell phone.

The threat was received at approximately 2:50 p.m., he said. The school then notified the San Luis Obispo County Sheriff’s Office “out of an abundance of caution,” he said.

“All students are safe and this appears to be a non-credible threat,” Prater said. “We deeply appreciate the rapid and robust response by the San Luis Obispo County Sheriff’s Department.”

The incident is still being investigated by the Sheriff’s Office.
