NAPERVILLE, IL — A man in his 70s from West Allis, Wisconsin, is in custody and charges are pending in the shooting of a conductor on the Naperville train station platform during rush hour Tuesday. The Amtrak conductor, identified as a 45-year-old Homewood man, was shot in the torso. The incident halted inbound and outbound BNSF trains near the Naperville Metra station, 105 E. Fourth Ave., on Tuesday evening.

The suspect's name had not been released, and charges against him were pending Wednesday, ABC Chicago reported. The alleged gunman was restrained by other passengers until police arrived, Naperville Cmdr. Lou Cammiso said. Police said the conductor was alert and conscious when he was transported to Edward Hospital in Naperville shortly after police responded at 4:45 p.m. Tuesday.

The suspect was inside the train when he reached through the window and shot the conductor, Cammiso told NBC Chicago. Police were reportedly investigating the gunman's motive.

A Twitter user posted a photo of a man being taken away on a stretcher near the station.
