The unidentified caller claimed to be enroute to Alpine Public School in Kitchener, Ayr Public School in North Dumfries and Baden Public School in Wilmot Township. The caller said they had weapons and threatened to hurt staff members and students. All three schools were placed into lockdown as a precaution and officers searched the buildings.
