Swatting incidents have occurred at Villanova and University of South Carolina in recent days. What is going on? What is swatting? What to know.

Authorities are investigating two reports of active shooters that were both deemed false at Villanova University over the last four days. The false reports prompted shelter-in-place orders as well as large police responses as the college outside Philadelphia began fall semester.

False reports of active shooters were made at universities across the country in the days leading up to the report at the University of Arkansas.
