Six people were in custody Friday evening, after a courier was robbed of $70,000 at a gas station in Cicero, Illinois, and the suspects led police on a car chase along the Eisenhower Expressway.

A Cicero police spokesman said multiple suspects in multiple cars approached the courier at a Mobil gas station that has video gaming machines around 3 p.m. in the 5100 block of West Roosevelt Road.

Employees at the gas station said the courier was trying to collect money from a slot machine inside.

Police believe the robbers stole about $70,000 in cash and fled the scene.

A townwide camera system, which uses license plate readers, helped police identify the cars involved, as a chase took over Chicago streets and expressways. Skywatch caught it all from the air and captured the cars traveling along the Eisenhower Expressway, around the Windy City Smokeout oustide the United Center, and under the CTA’s elevated Green Line tracks on the West Side.

At one point, police said one of the cars crashed into a Chicago police squad car at the intersection of Kostern and West End avenues in West Garfield Park, where two people were arrested. Another two people in a white Honda sedan ditched their car in an alley of a nearby apartment building.

Those two jumped out of the car, and one of them hopped over a fence as officers chased them on foot. They ran up the stairs of a three-story apartment building before they were captured.

Meantime, a black Chrysler that also fled the scene of the robbery was chased along the Eisenhower Expressway, Tri-State Tollway, Bishop Ford Freeway, and Borman Expressway into northwest Indiana, where two suspects were arrested after ditching the car in Hammond and running into the Little Calumet River.

Police said several bundles of cash were recovered from multiple vehicles and on the suspects.

Charges were pending Friday evening.
