The 16-year-old boy was charged with one count of mischief under $5,000 and is scheduled to appear in court in Red Deer on Nov. 12. He cannot be named according to the Youth Criminal Justice Act. On Sept. 1, the school was evacuated and firefighters were called around 2 p.m. after oleoresin capsicum was sprayed into a bathroom vent.
