A lockdown has been lifted after school officials say police were called to investigate a “threat of potential violence with a weapon” made towards an elementary school in Lake in the Hills.

Huntley Community School District 158 said Thursday in a message to parents that Hannah Martin Elementary School, located at 10920 Reed Road in Lake in the Hills, was put in a “hold in place and teach.”

The Lake in the Hills Police Department was called to the campus to assist the school administration in determining if a safety threat was present.

District 158 said an investigation was launched after a threat of potential violence with a weapon from an anonymous source.

Students and staff were continuing to learn in classrooms while the investigation was being completed.

Residents in the area reported that police had been at the school since late Thursday morning.

Marlowe Middle School and Chesak Elementary School, which are part of the Reed Road Campus, were not impacted by the investigation.

District 158 said that law enforcement and canine personnel conducted a thorough search of each classroom and school grounds.

The district said in an update that there is no active threat at the school following the sweep.

“Please be aware that your student may have been temporarily displaced from their classroom during the course of this search, but remained safe and supervised by staff,” the school district said in a message.

“Thank you for your continued patience during this time. We understand these situations can cause a degree of stress and uncertainty for our students and families and we appreciate your support as we work to maintain the safest possible learning environment for your child,” the district said.
