ComEd Incident Was False Alarm, Joliet Police Say

JOLIET, IL —There was no shooting at the ComEd plant on Briggs Street late Thursday morning, Joliet Police announced in a press release advisory sent to several Chicago area news outlets. At 10:18 a.m. numerous Joliet Police cars responded to the 1900 block of South Briggs Street for an active shooter alarm.

One Patch reader commented: "Something going on at ComEd on Briggs and 52, over 50 squads ... police are taking cover behind vehicles and have weapons drawn."

Joliet Police say they arrived on the scene and cleared the building. It turned out there was no shooter or similar threat.

"It was determined that the alarm, recently installed, was accidentally activated for an unknown reason causing the Joliet Police to respond," police announced later in the afternoon.
