Matteson police are calling an incident at the Greater Chicago Auto Auction on Friday morning, where a car hit a group of people, a "minor accident."
The incident occurred shortly after 9 a.m. An eyewitness said an auction employee driving a Mercedes SUV seemed to accelerate, hit a group of pedestrians, and struck a Maserati.
Four peple were transported to hospitals. One went to Christ Medical Center in Oak Lawn. Three others went to St. James Hospital in Olympia Fields.
A fifth person was also transported for what police described as an "unrelated matter."
Deputy Police Chief Michael Jones said none of the injuries appeared to be life threatening. The driver of the car was cited with "driving too fast for conditions."
The auction operates on a large site, some 138 acres.
