Several unlocked vehicles were broken into Wednesday morning in southern and unincorporated Dyer, police said.
The suspects of the thefts had Illinois plates and fled across state lines, according to a public announcement from the Dyer police.
The main targets were unlocked vehicles; in one case the thieves used a garage door opener in a vehicle to open an overhead door. The resident, alerted by the door opening, called police who came to the scene while the suspects were still in the neighborhood.
A suspect fled in a white KIA and led police on a chase into Illinois, according to Dyer police.
Dyer officers terminated the pursuit at Glenwood-Dyer Road and Burnham Avenue.
Dyer police implored residents to lock their doors, as car break-ins have been occurring from Chicago's west suburbs to south Lake County.
