Surveillance video shows someone wearing a mask trying a car door handle about 4 a.m. near Holly Avenue and May Street in Elmhurst. There are several people running in the background and white sedan without license plates rolling down the street.
About four unlocked cars in the area were burglarized, police said.
A similar incident in suburban Morton Grove led to shots being fired Wednesday morning.
The sedan was later seen driving quickly on eastbound Interstate 290, police said. It matched the description of a vehicle recently stolen in Chicago, police said.
The car was found abandoned on Chicago's South Side.
Elmhurst police reminded residents to lock their car doors and remove any valuables from vehicles.
