"There were more than a hundred people out here at the time of the shooting. So, we don't know how many people were actually involved in the fight that was taking place. It was pretty close to closing time. So, I believe there were a lot of people in the parking lot when it occurred," said Chief William Villanova, Oak Lawn Police Dept.
The alleged gunman was shooting at a vehicle when the security officers-- who are off-duty Cook County sheriff's police-- saw him.
A juvenile trying to get into that car was shot in the foot.
The man is in custody, but no charges had been filed Sunday evening.
