COUNTRY CLUBS HILLS, Ill. — Police responded to a Walmart parking lot in Country Clubs Hills following an armored car robbery attempt that resulted in an exchange of gunfire, authorities said Monday.

The shootout involved armored vehicle personnel, Walmart security personnel and unknown offenders, according to County Club Hills police.

SkyCam9 flew above the scene at 167th Street and Pulaski, where evidence markers were visible near the front entrance of Walmart. SkyCam9 captured the aftermath of an apparent collision involving the armored car and another vehicle, possibly an SUV, mere feet away from the entrance to the department store.

A witness who did not wish to be identified told WGN News that the alleged armed robbers targeted the armored car security. Amid the robbery attempt, however, witnesses told WGN News a shootout ensued, resulting in the shock and dismay of shoppers nearby.

“It’s heart-wrenching. It really is,” one woman told WGN News. “I don’t know what this world is coming to at this point, but this world is crazy.”

No one is in custody. According to reports, the alleged robbers carjacked a victim and fled the scene.

FBI Special Agent Siobhan Johnson told WGN News the carjacking victim does not appear to have been injured.  One of the attempted robbery suspects, however, may have been wounded, investigators say.  

The alleged armored car robbery comes after an earlier incident in Matteson at a US Bank on Lincoln Highway. Details remain limited.

No word on whether both incidents are related.

The FBI is assisting with both investigations.
