Police say a North Chicago High School student received a video of a subject holding a gun that had a caption indicating a shooting would happen on Friday.

Officials with the North Chicago Community High School provided information to the North Chicago Police Department on Thursday in regards to a threat made by social media.

The video was captioned “Shooting up nogo on June 3rd.”

In the video, a subject can be seen holding a gun and pointing it directly at the camera.
