Another school threat by a student was reported in the area, this time in Robinson.
Robinson Police chief Chad Weaver said a 13-year-old student made multiple vague threats to Nuttal Middle School, where the boy attended.
He said social media posts and comments from the student all led to a warning "not to come to school" on Tuesday.
Weaver said police triggered their threat assessment protocol and identified the student before classes started, while increasing security.
Authorities haven't named the student because he's a juvenile, nor have they said if he's back at the school or in custody.
