Several Lehigh Valley schools reported swatting incidents recently, when a caller reported a false active shooter situation.

The Pennsylvania State Police Troop M Bethlehem Patrol Unit responded to Catasauqua HS, located at 2500 West Bullshead Road, Allen Township, Northampton County, March 29 for a report of an active shooter within the school.

At 7:57 a.m., PSP Bethlehem received a phone call reporting there was an active shooter in Catasauqua HS and students had been shot. Multiple troopers from the Bethlehem and Fogelsville stations responded within minutes and cleared the school, and determined that there was no shooter and the call was a hoax.

The Pennsylvania State Police Bethlehem Criminal Investigation Unit is the lead agency in the investigation and is being assisted by the Federal Bureau of Investigation and the Catasauqua School Resource Officer.

Troopers will continue to have a visible presence at schools throughout the region for the remainder of the school year, state police said.

The Pennsylvania State Police office in Harrisburg reported investigating a series of phone calls made to 911 centers about schools across the state involving threats of an active shooter situation or bomb threat.

The phone calls, state police said, were made to several schools in different counties. All calls have had similar content. All calls are being thoroughly investigated and responded to by law enforcement.

“These calls have created lockdowns and/or evacuations of the schools with a large response from police and emergency services,” the release said.

All claims in these calls were determined to be false. All schools involved were cleared or by law enforcement.

The investigation is ongoing.
