A quiet Tuesday morning in Lisle turned tense when three armed suspects stormed the BMO Harris branch on Maple Avenue, triggering a heavy police and federal response and sending investigators on the hunt for clues. Witnesses told police the crew wore dark clothing and face coverings, then sped off in a black vehicle with an unknown amount of cash. No injuries were reported, and detectives are now combing through surveillance footage while urging anyone who saw something to speak up.
What investigators say
According to CBS News Chicago, the robbery went down around 9:30 a.m. in the 1000 block of Maple Avenue. Police say three suspects walked into the branch, pulled out firearms and demanded money, then bolted to a waiting black vehicle. The station reports that the exact amount of cash taken is still unknown and that no one inside the bank was physically hurt during the holdup.
FBI joins the search
FBI Chicago agents quickly joined Lisle officers at the scene, and a bureau spokesperson told Patch that the agencies were "responding to an incident in [the] vicinity" of the Maple Avenue block. Investigators are asking anyone with photos, video or other potentially useful details to submit tips through the FBI's online portal or by calling 1-800-225-5324. Officials say the case remains very active as agents review security footage and track down leads.
Local pattern of bank robberies
This latest heist lands in the middle of a broader pattern of suburban bank robberies that have pulled in multiple departments and jurisdictions in recent years. In 2023, CBS News Chicago reported that suspects tied to a DuPage County bank robbery were eventually traced to a Chicago warehouse. Federal prosecutors have also brought charges stemming from past Maple Avenue robberies, according to a U.S. Attorney's Office release, a reminder that these cases often leap across county lines. That history helps explain why Lisle police so quickly looped in federal partners this time around.
How to help
Investigators say even tiny details can matter. They are especially interested in surveillance or dash-cam video from businesses and drivers who were near Maple Avenue on Tuesday morning around the time of the robbery. Anyone with information is urged to contact the FBI tip line or submit a report online. Lisle police say community tips frequently prove crucial as cases move forward, and officials plan to release more information as soon as they are able.
