The Calgary Police Service is investigating what appears to be a swatting event involving an American high school.
Swatting refers to making a fake emergency call in order to provoke an emergency response.
Officers began receiving concerned phone calls about a Snapchat message allegedly threatening a high school around 7 p.m. Sunday night.
Police now believe the social media posts are related to a swatting incident in the United States aimed at Central High School, which bears a similar name to a school in Calgary.
In a statement, CPS says there is no reason to believe the threats are targeting any school in Calgary and officers will continue to work with law enforcement south of the border.
