Federal agent, CPD officer shoot 2 people during a "firearms trafficking operation" in Country Club Hills

A federal agent and a Chicago police officer shot two people during a "firearms trafficking operation" in Country Club Hills on Tuesday night. After the operation, five people were taken into custody. 

The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) said agents were conducting a "firearms trafficking operation" at 5:30 p.m. in the area of 189th Street and Lorreto Lane. 

Officials said an ATF special agent and a task force officer who is a member of the Chicago Police Department fired shots "in response to an attempted armed robbery of undercover agents" and hit two people. 

One neighbor said they heard three gunshots. Another said they saw a person running as agents were focused on the two shot.

Police said the two people were taken into custody and are being treated at a local hospital. Officials said their conditions were stabilized.

CBS Skywatch was over the scene Tuesday evening, where a white sedan was taped off, and a gun with an extended magazine was spotted lying in the middle of the street. 

The AFT said three other people were arrested at the scene. No charges were filed as of Wednesday.

The circumstances surrounding the initial operation are unknown at this time. 

The incident is under active investigation by Illinois State Police, the FBI and the Chicago Police Department. 

The Civilian Office of Police Accountability is also investigating.
