A high school in Orillia was locked down this morning over concerns that a weapon was brought into the building.
Just before 9:00am, Orillia Secondary School was locked down and OPP did a thorough sweep of the school, searching for weapons.
When no weapons were found, police reopened the school a little over 25 minutes later.
The complaint had originally been called into OPP, and the cause is being investigated.
