Police followed the man up to a third floor apartment. Police said there was a brief struggle, the man left the apartment and the officer fired one shot which struck the man in the neck. The man did not fire at officers.
The man was taken to University of Chicago Trauma Center in serious condition, police said. Police said they recovered a semi-automatic 9 mm gun with an extended clip from the scene.
