Police are on the scene at St. John Vianney School in Windsor.
A spokesperson for the Windsor-Essex Catholic District School Board says staff and students at the school on Cedarview St. near Dieppe St. have been moved across the street to John Vianney Parish.
Stephen Fields says “they will not be allowed to go back in the school until police have given the all clear.”
The school board also says there is no need for parents to go to the church to pick up their children.
No word on exactly what the threat is at the school.
Windsor Police have tweeted about the situation and only say they are investigating an unsubstantiated threat.
