Authorities have cleared Montebello High School after an alleged threat prompted a lockdown at the campus Thursday afternoon.

Police and school officials sent alerts around 3:30 p.m. informing parents and the public of the situation but did not say what the alleged threat was.

At the time, police said “the credibility of the threat is being assessed.”

At 6 p.m., the Montebello Police Department tweeted that the campus and students were safe and that an investigation was ongoing.


Principal Tino Duarte sent a statement to parents at 3:30 p.m.

“Our administration received a threat via telephone regarding Montebello High School,” Duarte said in the statement. “Out of an abundance of caution, Montebello High School is on lockdown while the threat is being investigated.”

Angel Barnuevo, a Montebello Unified School District spokesperson, told The Times students were later dismissed classroom by classroom.

Authorities did not provide further information about the case on Thursday. Police could not be reached for follow-up questions.
