A number of school districts around the country are responding to an anonymous threat on TikTok that seemingly warns against students attending class on Friday.
The threat, or “challenge,” as some have referred to it, reportedly calls on students to commit acts of violence on Dec. 17. According to Syracuse.com, the threat labeled December 17, “National Shoot Up Your School Day,” and does not name a specific school or district.
While PEOPLE was not able to identify the TikTok post where the threat originated, there are now hundreds of other TikTok posts referencing the challenge and warning students to take precautions.
