A threat to “just kill everyone” at Van Nuys High School was determined to be non-credible by Los Angeles School Police, a school district spokeswoman told the Daily News Monday.

Even so, out of an abundance of caution over the the Snapchat-delivered threat, additional school police will remain assigned to the Cedros Avenue campus, said Los Angeles Unified School District spokeswoman Barbara Jones.

The threat posted on Snapchat about 8 p.m. Sunday quickly went viral as students and parents passed it around on multiple social media services. The non-credible threat has the San Fernando Valley campus on edge today, with Los Angeles police out in force.

The Snapchat threat — which also included the words, “First you guys. Yup when I put this bullet in to head” — was revealed late Sunday on CBS2’s 11 p.m. newscast.

“Yesterday at about 8 p.m., the Van Nuys Division received information regarding a threat at Van Nuys High School,” LAPD Detective Ross Nemeroff, a spokesman, said Monday morning. “It was generated through a social media site. Officers completed a preliminary investigation, and the case is now turned over to (LAPD’s) Major Crimes Division.”

No suspect was in custody early today and “the department is working on identifying the suspect who posted the social media threat,” Nemeroff added.

Sgt. Nestor Gonzalez, watch commander of the Los Angeles School Police Department, confirmed with the Daily News that the threat came over Snapchat.

The social-media service from the LA-based Snap company features messages that disappear once they are seen by recipients.

“The most important thing to remember is that all threats are taken serious(ly), and we’re doing our best to resolve this issue,” Gonzalez said. “Every (such) call is investigated — we don’t leave any stone unturned.”

The high school campus on the 6500 block of Cedros Avenue is bordered by Kittridge Street to the north, Kester Avenue to the west and Gilmore Street to the south.

While classes were not canceled, one parent who spoke to CBS2 planned to keep his 13-year-old child out of school due to the threat.

The threat was made by a Snapchat user whose name on the service is Ashely Smith.

More to come.
