Editor’s Note: Although our website has been filled with April Fools’ jokes all day, this story is, in fact real.

A prank text message put State College Area High School in lockdown this morning. State College Police were dispatched to the school at 9:06 a.m. following a report of a shooter in the school, according to a release.

Superintendent Bob O’Donnell released the following statement to SCAHS families.

“This morning, a high school student played an April Fool’s joke on her parent. Specifically, she texted her parent that a “shooter” was in the high school south building. This prompted a 911 call. The student admitted it was an April Fool’s prank. Please know that the 911 service initiated an immediate response by the State College Borough police. We had our in-house State College Borough police officer immediately assessing the situation first-hand with principals and the student. Emergency protocols were followed.”

School officials responded to concerns on Twitter.
