Livermore High student arrested after allegedly threatening harm to classmates

A Livermore High student has been arrested for allegedly making a threatening statement, the district announced.

An unidentified student "made an alarming statement to other students, threatening to cause harm on our LHS campus," the Livermore Valley Joint Unified School District said in a message to parents Thursday.

The disturbing exchange was immediately reported by students to the LHS administration and Livermore Police Department, which launched an investigation.

Dr. Kelly Bowers, Superintendent of Schools, included the following in the statement:

"Thanks to the thorough and swift response of the investigating officers who worked throughout the night, an arrest has been made. The individual who made the remarks remains in custody and we are confident that any possible threat has been neutralized. School and activities will proceed as usual without interruption."

Authorities would not go into details about the nature of the threat. But Bowers said it involved "some weapon. It definitely wasn't an explosive."

Bowers credited three student-athletes who notified a member of the school staff about what they heard. The staff called police.

"We commend the students who came forward in keeping with our ‘See Something, Hear Something, Say Something’ mantra to ensure our high school campus remains a safe and secure place for all students and all staff at all times," Bowers said.

Livermore police spokesman Arturo Rosas said officers conducted an investigation into the allegations and found that the student had made "substantial threats." The teen was arrested and taken to juvenile hall, Rosas said.

Bowers said the alleged threat was supposed to take place Thursday.

Additional police cars sat outside the high school that day. They were mostly there to help calm any fears students and staff may have had.

This incident comes during a difficult time for LHS students as they deal with the aftermath of a tragic car crash involving their classmates just a few weeks ago.

One student was killed and five others injured in that crash.
