Police officials say a report of a gun being brought to Huntley High School prompted the Wednesday lockdown. No credible threat was found, police added.

Huntley High School Principal Marcus Belin said in an email to parents that the school was put in a “hold in place” lockdown around 1:45 p.m. Wednesday.

“At this time, common spaces and hallways have been cleared and students remain supervised and learning in classrooms,” Belin said.

The Huntley Police Department was called to the school to investigate a “potential safety concern,” Belin said.

Huntley Deputy Police Chief Linda Hooten said officers received a report of a potential weapon being brought to the campus.

Leggee Elementary School, which is also located on the Harmony Road Campus, was placed on a “Secure the Building and Teach” while the incident was investigated.

No students, staff or parents were permitted to leave or enter the high school during the incident, police said. Transportation services and dismissal were postponed.

School administrators and the Huntley Police Department determined around 3:15 p.m. “no credible threat to student or staff safety was present,” Hooten said.

Hooten added that the report of a gun came in from a third party and the investigation did not substantiate that there was any weapon or threat.

Students at Huntley High School were dismissed by a staggered release with increased police presence.

Students at Leggee Elementary were also dismissed when no threat to safety was determined. Officials directed traffic to alleviate delays for families.
