Authorities have cleared an Orange County high school after an anonymous bomb threat was made Thursday morning.
A sweep of the campus was completed in the afternoon and nothing suspicious was found, officials said. The school lockdown was expected to be lifted at 1 p.m.
A bomb squad responded to the reported threat around 9 a.m. at San Clemente High School located at 700 Avenido Pico.
Students sheltered in place as a precautionary measure, according to a statement on the school's website. Parents were asked not to go to the school as law enforcement investigated the threat.
Parents would be notified if students need to be removed from campus, the statement said. School officials said parents would be updated with information through phone messages, emails and on the website.
The threat was discovered on downloadable social media app “Yik Yak,” according to a tweet from the Orange County Sheriff's Department.
Parents were told to call (949) 234-5575 if they had more questions.
About 2,900 students attend the school.
