A few minutes of fear at the public high school in Angus yesterday, after a threatening message about the school was posted to the social media site, Snapchat.
The message suggested students not go to school on the 16th.
OPP and Barrie police were involved in the investigation, and figured out who had posted the message. They also say there was no intent to carry out any kind of attack.
Police now say there's no worry about public safety, but don't say whether any charges were laid in the case.
