Groton — Town police investigated a potential threat at Fitch High School on Wednesday morning after an anonymous tip that a student had a gun and a bomb, but the report was false.

According to a police news release, a juvenile eventually was charged with first-degree falsely reporting an incident, first-degree threatening and second-degree breach of peace.

The school resource officer received information about the threat about 8:45 a.m., at which point members of the Patrol and Criminal Investigations Division responded to the school to investigate.

"During the course of the investigation numerous witnesses were interviewed and a juvenile suspect was identified and found to have been the source of this information," the release reads. "The investigation revealed that the subject intentionally falsely reported the threat and that the details were not credible."

School officials also "took measures to ensure the safety of all the children in the school," according to Groton school Superintendent Michael Graner.

"The principal is notifying the parents that there was an incident that was not credible and that the children are safe," Graner said. "At no time did we ever think there was a credible threat."

Students were not sent home. Authorities determined that there was no threat to the school.

The unidentified juvenile was given a juvenile court referral and released to his or her guardian.
