Police departments in Minneapolis and Chicago are contending with a flurry of smash-and-grab crimes that investigators say increasingly involve juveniles and stolen vehicles. Minneapolis Police Chief Brian O’Hara said more than 500 parked cars have had their windows smashed this year, with more than 100 reports filed overnight into Tuesday alone. Officers recovered two stolen vehicles and arrested three juveniles on Aug. 19 in connection with the spree, and the department has activated its Crime Pattern Response Protocol to curb further vandalism. In Chicago, detectives are probing two break-ins early Wednesday. A box truck was used to ram barricades at a clothing store in the Ukrainian Village neighborhood around 1:48 a.m., after which thieves fled in a black sedan. Earlier Tuesday, a South Side Foot Locker was hit by a group of burglars, and another West Side retailer reported a similar overnight incident. No arrests have been made in the Chicago cases. Authorities in both cities say the incidents reflect a broader trend of coordinated, fast-moving property crimes, often carried out with stolen vehicles to facilitate quick getaways. Investigators are reviewing surveillance footage and sharing intelligence across jurisdictions as they look for links among the crews involved.
