​Harrisburg, PA – The Pennsylvania State Police (PSP) is investigating a series of phone calls made to 911 centers about schools across the Commonwealth involving threats of an active shooter situation or bomb threat.

These phone calls 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 PSP has responded to all incidents in our primary coverage areas and has been in contact with municipal law enforcement partners investigating these incidents in their coverage areas.

At this time, all claims in these calls have been determined to be false. All schools involved have been cleared or are in the process of being cleared by law enforcement.

The investigation is ongoing.
