According to the Riverside Police Department, officers launched a School Threat Assessment and Response (STAR) investigation Monday night after parents from Central Middle School flagged a concerning Instagram post.

Police said the post showed a student holding what looked like a gun and contained a list of classmates’ names. Investigators worked through the night to identify the boy with help from the school resource officer.

According to police, a search of the student’s home uncovered a “realistic” toy gun, and the boy was arrested and booked into juvenile detention on suspicion of making criminal threats and conspiracy. Investigators said they expected a second student would also be charged with conspiracy.

The arrest comes amid a wave of similar social media threats reported in Southern California and nationally in recent weeks, leading to the arrests of students as young as 11.

Police in Riverside ask that threatening posts be reported to the city’s non-emergency line at 951-354-2007. Social media posts that suggest potential school violence, but without a specific threat, can be reported via the Atlas 1 mobile app.

The incident in Riverside is the latest in a rash of threats plaguing California schools in recent weeks, prompting police investigations, school lockdowns and arrests of suspects as young as 11. Over the last week, authorities have also investigated non-credible threats at schools in the Bay Area and in Los Angeles, Orange, and San Diego counties.

In Riverside, where a student was recently for allegedly making threats at Arlington High School, police said another incident happened Friday at Chemawa Middle School.

“This caused significant concern among parents, prompting many to withdraw their children early due to safety fears,” the department wrote on Facebook. “Our school resource officers promptly launched an investigation to trace the origin of this threat and ensure the safety of the school community.”

Police said tips rolled in over the weekend concerning a student believed to be responsible for the threat. On Tuesday, the school resource officer identified a 13-year-old girl as the alleged culprit. She is accused of posting a threat on social media, followed by a second post naming “targeted classmates.”

According to investigators, a search of the girl’s home confirmed she had no access to weapons. She was booked into a juvenile detention facility on suspicion of making criminal threats. Following the arrest, police leaders reiterated the serious consequences of making any kind of threat, even if it turns out to be a hoax.

“These recent disruptions to our schools must stop immediately so that our children can focus on their education,” said Larry Gonzalez, Riverside’s police chief. “Students who make threats of school violence on social media or by other means will face strict criminal consequences and severe disciplinary action, up to and including expulsion. We will not tolerate any behavior that undermines the safety and security of our schools.”
