Lakehead Public Schools had to put two schools under a brief hold and secure on Friday.
McKenzie Public School and Algonquin Avenue Public School were secured for less than an hour as a result of possible dangers caused by two separate off-property incidents that were unrelated to the schools.
City police cleared Algonquin Avenue Public School and the provincial police cleared McKenzie Public School.
The quick resolution of the incidents allowed both schools to continue with a normal day.
