The Nishnawbe Aski Police Service say they are investigating a threat received this past weekend on the Attawapiskat First Nation.

During the playoffs of a hockey tournament, an arena attendant found a folded-up note with the message “Shooting Up Arena 7 pm”.

Five NAPS police officers were dispatched bearing rifles, to ensure the safety of the people attending the tournament.

Fortunately, police say the rest of the tournament was played without incident.

A copy of the note can be seen below.
