A mysterious backpack in a second-floor men's washroom was enough to put Lane Tech College Prep on alert Friday, briefly pushing the massive Northwest Side campus into a soft lockdown and drawing a hazmat response from Chicago police and firefighters. By the time the dust settled, officials were calling the threat non-credible and stressing that no students or staff had ever been in danger.
Unknown Object Sparks Soft Lockdown, Hazmat Call
Firefighters were called about an "unknown object" inside the school at 1:25 p.m., and the situation was quickly upgraded to a level 1 hazardous-materials response, according to the Chicago Sun-Times. The response was secured at 1:44 p.m.
Police radio traffic reviewed by the paper indicated Lane Tech shifted into a soft lockdown during sixth period. Some students were moved to another building while crews checked out the scene and evaluated the object.
Officer reports obtained by the Chicago Sun-Times state that a Chicago police officer detained a person after the backpack was discovered in the men's washroom on the second floor. No injuries were reported.
Principal Tells Families Threat Was Non-Credible
Principal Edwina Thompson moved quickly to calm nerves, telling families that the incident did not put anyone at risk.
"No students or staff were in danger," Thompson wrote, adding that "all after-school activities are expected to proceed as planned," according to the Chicago Sun-Times. Once authorities cleared the scene, the school said activities could move forward on schedule.
Big Campus, Big Response
Lane Tech is one of Chicago's largest high schools, with thousands of students and staff navigating its sprawling campus on a typical day. That scale helps explain why multiple agencies rolled in so quickly and why some students were relocated while the object was being assessed, according to Lane Tech.
Officials ended the day emphasizing what did not happen: there were no injuries, the suspicious object did not result in harm, and the threat was determined to be non-credible. School leaders urged families to keep an eye on Lane Tech's official channels for any further updates, but by late afternoon the message was clear the scare was over and the school was back to business as usual.
