December 17 school threat hoax

DEC 17 2021

A vague, unattributed post warning of school shootings on 17 December 2021 circulated on TikTok and other platforms, naming no specific school. The Department of Homeland Security said it had no information indicating a specific credible threat, and police departments publicly identified it as a hoax. Districts in several states nonetheless closed for the day or increased police presence.
