Additional security will be in place at Hart High School in Santa Clarita on Monday following a recent reported threat, authorities said.

While the threat does not appear credible, additional deputies have been assigned as a precaution to the campus at 24825 Newhall Ave., according to the Los Angeles County Sheriff’s Department.

According to a parent of a student at the school, the threat was written on a bathroom wall and named a specific student and a date.

“Friday afternoon, we discovered a threat to Hart High School written in one of our campus washrooms,” school principal Jason d’Autremont wrote in an email to parents on Sunday. “We have contacted law enforcement and are investigating the issue.”

“At this time, we don’t have specific details to share, but we wanted you to know that we are investigating the threat and have notified the family of a student whose name has been listed.”

The school will remain open throughout the week, with an increased police presence in place. The Sheriff’s Department is investigating the threat.

Earlier this month, four Hart students under the age of 18 were arrested after one of them was allegedly in possession of a gun on campus.

After receiving a credible report via their anonymous reporting line, school officials and the Santa Clarita Valley Sheriff’s Station reported finding a student allegedly in possession of a gun and taking him into custody. September 8.

According to principal Jason d’Autremont, the investigation began when administrators learned through their anonymous whistleblower line that a student had been seen in a photo on social media in possession of a gun.

The names of the students – two boys and two girls – have been withheld by police because they are minors.
