The Warren County Sheriff’s Office, Pennsylvania State Police, and Warren County School District officials responded Thursday to a school threat posted on social media.

According to the Sheriff’s Office, the agencies addressed a Facebook post that indicated an incident was to take place Thursday at Eisenhower Elementary, Middle, High School.

“Last night, the Sheriff’s Office received a call from a concerned parent advising that one of her children had observed a threat that was to take place today,” according to a post on the Sheriff’s Office Facebook page. “The call was forwarded to 911 and the Pennsylvania State Police. Warren County Sheriff’s School Resource Officers and school district officials were notified.”

“A plan involving all the agencies was put together and carried out this morning at the Eisenhower campus, according to the post.

Superintendent Amy Stewart said the agencies worked together into the night and that the district’s call blast system was used to make parents and staff aware starting at 6 a.m.

“Sheriff’s deputies and K-9 Dina, troopers, and school district officials were all on hand,” according to the Sheriff’s Office. “Sheriff (Ken) Klakamp reminds all county residents to report any type of threat to law enforcement agencies regardless of how minor it may seem.”

The incident is under investigation.
