Police were called to Zion-Benton Township High School after it was placed on lockdown Thursday morning following a threat made to the school.

The Zion-Benton District 126 issued a precautionary hard lockdown around 9:10 a.m. Thursday.

A “vague” threat was made against the high school, the district said without specifying further.

The Zion Police Department and Zion Fire-Rescue Department were called to the scene.

The school district said just after 10 a.m. that the lockdown had been lifted and classes would resume their normal schedules.

Police verified there was no credible threat or immediate danger.

The district said police will continue to investigate the “apparent hoax” that disrupted the school day.

Officers are providing extra patrol on school grounds following the incident.

Students are remaining in a soft lockdown for the remainder of the day as a precautionary measure.
