A student with a knife was detained on a Santa Rosa middle school campus Wednesday. 

According to the Santa Rosa Police Department, Officer Luigi Valencia, who was assigned to Herbert Slater Middle School, was meeting a student who was experiencing a mental health crisis in the school’s office when he was informed that an unknown juvenile was on campus. 

According to the police, a physical education teacher made contact with a juvenile male that he did not recognize on campus. 

When the school officials were informed about the trespasser, the unknown juvenile started walking away from the area. 

Another staff member followed the juvenile off campus and onto Sonoma Avenue, police said. He was able to convince the juvenile to stop.

Officer Valencia caught up with the staff and the juvenile a few houses away from the campus. 

Investigation reveals that the student possessed a folding knife 

The juvenile, identified as a 14-year-old student at Comstock Middle School, was arrested and booked into Sonoma County Juvenile Hall and charged with possession of a knife on school grounds.
