Police said Jones used an assault rifle to fire five shots at a moving CTA train as it pulled into the station in the 100-block of West Congress Parkway around 11:20 a.m. Thursday.

Jones was arrested a short distance away from the scene. Police seized a .45-caliber assault rifle and said they found 60 rounds of ammo in Jones' pocket.
No one was injured in the shooting.
Jones, of the 7500-block of South Luella Avenue in Chicago, was charged with aggravated assault with a firearm, aggravated unlawful use of a gun, aggravated unlawful use of a gun with access to ammunition and possession of a stolen firearm.
Chicago Police Superintendent Garry McCarthy said before charges were filed that the suspect was targeting the train, not passengers. He described the man's behavior as "kind of bizarre" and said he didn't know his motive.
McCarthy said he had a valid firearms owner identification card but the weapon he used was stolen from Indiana.
Jones is due in bond court on Friday.
