A 19-year-old Santa Monica College student was arrested in connection with threatening to "shoot up the school" at the Santa Monica College's Pico campus, officials said.
The Los Angeles County Sheriff's Department tweeted that a suspect was arrested in connection with a threatening phone call about East Los Angeles College.
Santa Monica College officials said in a campus message sent to students and others that the lockdown there was lifted at 9:42 a.m. Campus police detained the student who made the threatening phone call to the college campus there.
The threat prompted lockdowns and at least one evacuation at schools in LA, Monterey Park and Santa Monica, officials said.
The lockdowns began shortly after 8 a.m.
Lockdowns were put into place at the Santa Monica College Pico campus, East LA College and other schools in Monterey Park and Los Angeles. Streets around the schools were shut down.
Up to 30 Los Angeles County Sheriff's Department personnel, which patrol community college campuses, plus school police and Monterey Park police responded to the East LA College campus.
Officials were taking the security measure as a precaution.
"I'd like to stress there has been no specified person or threats found," said Nicole Nishida, a spokeswoman with the Los Angeles County Sheriff's Department. "They'll be going through every area and every room and running down the phone threat."
