Police say a 16-year-old male and 17-year-old female were charged with assault, a second 16-year-old female was charged with uttering threats, and a 36-year-old female is accused of causing a disturbance.

Police say the adult charged is not a school employee.

The hold-and-secure was a precaution, according to police. It’s used when there is a threat in the general vicinity of a school. The outer doors of the school are locked while classes continue, and students are generally considered safe indoors.
