A Chicago police officer remains hospitalized Wednesday after being shot following a bank robbery in Des Plaines and a chase that ended on the Northwest Side.

The bank robbery suspect was fatally shot and a teenager who was at the scene was also wounded, WLS reports.

It started with a bank robbery Tuesday in Des Plaines, with police taking one suspect into custody and a second suspect escaping after stealing a car at gunpoint.

FBI agents and Des Plaines police chased the suspect down the Kennedy Expressway and alerted Chicago police. CPD officers were waiting when the suspect exited the expressway at Irving Park Road shortly before 7 p.m., police said.

"Upon seeing CPD, the offender fired at the vehicles, at which time a Chicago police officer suffered a graze wound to the temple of his head in the exchange," Chicago Police Superintendent Eddie Johnson said. Police later revealed the officer's injury was much more serious than first thought. The bullet actually penetrated and exited his skull and he has a skull fracture and bleeding on the brain.

The 46-year-old officer remains hospitalized at Illinois Masonic Hospital in serious but stable condition. Police said he is a highly decorated 17-year veteran of CPD who works out of the17th District in Albany Park.
