An elementary school in Highland Park was evacuated Thursday and a large police response was sent following a bomb threat that has been determined to be unfounded.
The Highland Park Police Department and Highland Park Fire Department responded around 7:50 a.m. Thursday to Red Oak Elementary School, 530 Red Oak Lane, for a report of a bomb threat.
The City of Highland Park said in an initial statement that a large police presence was at the school to facilitate an investigation.
Residents in the immediate area were advised to avoid Red Oak Lane, which was closed at Rosemary Road and Ridge Road.
North Shore School District 112 delayed the start time for students by two hours due to the threat.
City officials said in an update around 10:30 a.m. that police personnel and a team of explosive-detecting dogs conducted a search.
The search did not locate any devices in the school and the threat was deemed not credible.
Officials did not say how the threat was received or if it is related to other bomb threats throughout the Chicagoland area this month.
The school district reported that Red Oak School would resume normal operations at 11:30 a.m.
The incident remains under investigation by the Highland Park Police Department.
