A soft lockdown was put into place Wednesday afternoon at Lake Zurich High School after a shell casing was found. The lockdown has since been lifted.

Lake Zurich Community Unit School District 95 said in a statement the soft lockdown was issued “in an abundance of caution.”

The Lake Zurich Police Department was called to the school to assist school officials in the investigation.

“As a standard response, while we investigate, students and staff will remain in a soft lockdown. This means instruction will still continue; however, students will remain in their assigned location, and no visitors will be allowed on or off campus at this time,” the district said in the statement around 12:20 p.m. Wednesday.

The lockdown was put into place after a shell casing was found at Lake Zurich High School.

School officials did not say where the casing was found. They urged parents not to go to the school during the lockdown.

Just over an hour after the initial statement was sent to parents, the school district said in an update they had lifted the soft lockdown.

The updated statement from the district said there was no identified threat to the school campus and no guns were located.

Officers with the Lake Zurich Police Department will continue to be at the high school for the remainder of the day.

The district added that students would be returning to classes in a revised schedule in order to accommodate those who missed lunch due to the lockdown.
