Police have laid charges after nearly 50 schools in the region were placed under Hold and Secure.
A 16-year-old Gravenhurst male who was arrested yesterday by Bracebridge OPP has been charged with mischief and uttering threats.
Police made the arrest after the Trillium Lakelands District School Board received threats over social media.
The school board placed all of its schools into Hold and Secure for about two hours on Friday morning because of these threats.
The name of the male cannot be released due to the Youth Criminal Justice Act.
