RIVERSIDE, Mo. -- A morning drill ended with a new threatening message inside a school district in the Northland. Riverside Police say someone used a Sharpie to write a note on the wall of a stall in a girls’ bathroom, but officers don’t believe the threat is credible.

Riverside Police were already on campus Thursday morning, partnering with the school for an active shooter training drill, similar to a fire drill. In an active shooter case, students and teachers are taught to lock down in their classrooms. Police tell say it was right after this drill, some students found the writing in the bathroom.

Park Hill Schools posted a notice on their website, and both called and emailed parents with the same information. In part, the statement says "police plan to increase their presence at the school tomorrow.” The district also thanks "the students who came forward to report the threat and keep their school safe."

“The safety of students is the top priority. We will have extra patrols at Park Hill South High School Friday,” Sergeant Jack Minor said.

This is the third threatening message found on the walls of a Park Hill school in a matter of weeks. Earlier this month a student came forward after leaving threatening graffiti on the halls of Plaza Middle School. A few days before that incident, another threatening message was found at Park Hill South High School. Police arrested a student for that threat.
