A wave of hoax active shooter calls, known as swatting incidents, has targeted at least 11 college campuses across the United States since August 21, 2025. Universities affected include the University of Colorado Boulder, University of Arkansas, Northern Arizona University, Iowa State, Kansas State, University of New Hampshire, and Texas Tech. These calls often feature fabricated reports of gunshots and have triggered campus-wide shelter-in-place orders and law enforcement responses, though no injuries or suspects have been found. The FBI is investigating these incidents and has urged students to remain vigilant. Intelligence reports indicate that at least 10 of these hoaxes are linked to a single online group called Purgatory. Experts warn that such swatting hoaxes are expected to continue and potentially worsen over the next two months. The incidents have caused widespread fear among students and have drawn calls from lawmakers for severe legal consequences for those responsible.
