MEDICINE HAT — Police in southern Alberta say a high school has closed and several others are locked down after some students received an anonymous threat.
Medicine Hat police say five students received the threat by text on Sunday night.
They say the message referred to potential harm to the students.
A news release says officials with Monsignor McCoy High School voluntarily chose to close the school for the day and students were sent home as a safety precaution.
