Students at schools in the Coseil scholaire de district catholique des Aurora boréales have been sent home following a threat made overnight.

In a social media post the board says it received a dubious message with threats.

Ten schools are affected including at Franco-Supérieur and ÉSC de La Vérendrye in Thunder Bay, École Catholique des Étoiles-du-Nord in Red Lake, École Catholique de L’enfant-Jésus in Dryden and Ecole Immaculée Conception in Ignace.

Parents are asked to pick up their children as the schools are now closed.

A spokesperson with the board says police are investigating the threats.
