The Orange County Sheriff's Department bomb squad was called out to Capistrano Valley High School in Mission Viejo this morning after school officials discovered questionable materials in a student locker, officials said.
Lt. Jeff Hallock of the OCSD said after a student was suspected of a theft, school officials searched his locker and found what was first interpreted to be chemicals used to extract THC from marijuana.
The bomb squad showed up to investigate, and students were on lock down in their classrooms, but the alert proved to be a false alarm, Hallock said.
"It was more of a precautionary action," he said.
One parent posted on Facebook: "They separated the student from the chemicals. Bomb squad is here, along with significant number of sheriffs. It looks like there is some sort of modified containment (can't even call it a lockdown) at the high school. Kids are moving around in large groups. ...
"Very impressed with how my son's school handled everything from A-Z. I just happened to walk in the exact same moment they were locking down the campus. I am confident everything is under control."
