WARREN, Ohio (WKBN) – Students at a Warren school were evacuated Wednesday afternoon following a “threatening” message.

According to Warren Police Chief Eric Merkel, a bomb threat was made to Jefferson PK-8 School and a shooting threat came into John F. Kennedy High School.

Threats have also been made toward a Niles school as well, and Niles Police and Warren Police are working jointly to investigate.

“We are aware that there have been multiple threats being made towards our schools. We are investigating alongside Niles Police Department who has also received threats to a school in their jurisdiction. We are currently working collaboratively with Niles Police and the Trumbull County Prosecutor’s Office to resolve this situation and it’s an ongoing investigation,” said Det. Michael Altiere with the Warren Police Department.

The schools are expected to have extra police present during classes Thursday.

Superintendent Steve Chiaro confirmed that students at Jefferson PK-8 School were taken by bus to another school location Wednesday afternoon, along with their teachers and administrators.

Dozens of parents gathered around Jefferson and some were upset, saying they felt they should have been notified sooner.

“If y’all would’ve just let us know before my child can call me and tell me something is wrong and I don’t know, and my child is telling me he’s scared. As soon as y’all alerted the police to let the police know y’all should’ve been sending something out to the parents,” said Jasmine Williams, whose sixth-grade son goes to the school.

Williams said the only reason she knew her son wasn’t at his school was because she got a notification that his location was somewhere else.

“I got my neighbor, we went to Harding, then they told us, ‘Oh, well, we called people and we also emailed people.’ We never received anything. While me, my neighbor and other parents was up there, then that’s when they took initiative to send out a mass email and/or a phone call,” Williams said.

Warren police investigated and cleared the building for students to safely return and dismiss as usual. Chief Merkel says they are still investigating where the threats came from and have not made any arrests as of yet.

In Niles, police were called to the school after officials were made aware of a threat posted on Snapchat by an unidentified male that were similar to the threats made in Warren.
