Police are on location at Huntley High School searching the school, which was placed on lockdown, following an unspecified “safety concern,” authorities said.

Huntley High School Principal Marcus Belin said Wednesday afternoon in an email to parents that the school was put in a “hold in place” lockdown.

“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.

“There is no current threat to student or staff safety at this time,” he added.

The Huntley Police Department said the school was still in lockdown as of 2:35 p.m. Wednesday.

No students, staff or parents are permitted to leave or enter the building, police said. Transportation services and dismissal are currently postponed.
