DES PLAINES, Ill. — A north suburban high school is on lockdown after the “active shooter” alarm went off accidentally, the school district said.
Police are on the scene at Maine West High School in Des Plaines, but they have not identified a threat, Maine Township High School District 207 said in a statement.
The district said it believes either someone accidentally pushed the button, or there was a short in the system that caused the alarm to go off.
Still, the school is on lockdown “to keep students and staff safe” and to keep in line with protocol, the district said.
Chopper 7HD is over the scene, where students are being escorted out of the school.
The district said parents should not come to school. Police are actively clearing the building.
