An investigation was underway Wednesday after an email from a student’s account apparently threatened violence on campus, police said.

The school received an email around 10 p.m. Tuesday that allegedly stated there would be explosives hidden on campus, Fountain Valley Police Department Sgt. Tony Luce said.

The email also allegedly said any survivors would be killed with an assault rifle, according to Luce.

Police interviewed the student, who was cooperative with authorities and claimed he did not send the email, Luce said.

The student gave police his phone and computer, and officers were looking into the possibility that the email account was hacked.

Luce added that student did not have access to firearms.

A bomb squad was sent to check out campus as a precautionary measure.

Classes at Fountain Valley High School were canceled for the day following the threat, the school announced on its Facebook page.

“Classes cancelled today. Due to a threat received overnight, the Fountain Valley Police Department has closed access to the school,” the post stated.

The school would remain closed for the rest of the day while the bomb squad searched the campus, Luce said.

In a separate statement posted to the school’s Facebook page, Principal Chris Herzfeld said, “Out of an abundance of caution, FVPD is going to sweep the entire grounds. It will take hours.”

Herzfeld added he would send an update later regarding afternoon activities on the school’s campus.

A parent of a student at the school told KTLA they received an automated phone call regarding the closure.
