Lemont police suspect that someone hacked into the village’s tornado siren system, causing all seven sirens to sound for about 30 minutes, Police Chief Kevin Shaughnessy said today.
Three sirens were activated inexplicably in Evanston at 7:30 p.m. Saturday night, including two at fire stations, officials said.
“Those sirens can only be triggered by our 911 dispatch center,” said Dwight Hohl, the city’s Division Chief of Life Safety Services. “It’s not something that just anyone can do. We’re not certain on the source.”
