Marlowe Middle School in Lake in the Hills was on lockdown Thursday morning while police investigated a live round of ammunition that was found on campus.

The school, located at 9625 Haligus Road in Lake in the Hills, sent an email to parents around 8:30 a.m. Thursday about the situation.

Officials said in a statement that the school was put into a “Hold in Place and Teach” lockdown.

The Lake in the Hills Police Department responded to the school after a live round was found on campus, police officials said.

Common spaces and hallways were cleared and students were supervised and learning in classrooms, school officials said.

“Any medical and personal comfort needs are being met on an individual basis, and an alternate plan for lunches is in place in case food needs to be served in the classrooms today until we are given the all clear by the Lake in the Hills police department,” the statement said.

The school announced just before 11 a.m. Thursday that the lockdown had been lifted after police deemed that no safety threat was present.

Law enforcement conducted a “thorough search” of the building and grounds with canine personnel present.

There will be an increased police presence on campus for the remainder of the day.

“During this time, students continued safely learning in classrooms and will now be able to move freely throughout the building as normal. Lunch periods have begun in a normal grab and go style and students will follow their normal schedule for the remainder of the day,” the school said.
