College campuses across the country descended into chaos this week as false reports of active shooters sparked mass panic, lockdowns, and major police responses – only to be revealed as coordinated hoaxes.

On Monday alone, at least six universities reported active shooter alerts. All turned out to be false alarms, but not before causing widespread disruption and fear.

“Swatting threats are not hoaxes – they’re serious. They disrupt the educational process and communities into upheaval,” Ken Trump, the President of National School Safety and Security Services, told Fox News Digital.

North Arizona University was one of several schools which were victims of swatting hoaxes on Monday.

The university reported that campus police received a report of a person with a gun at Cline Library on the Flagstaff mountain campus.

“The report was determined to be a hoax, and at no time was there an active threat to the NAU community,” the school wrote in a news release.

An investigation is underway into the false report with assistance from the Federal Bureau of Investigation (FBI), the school said.
