A man who fell onto the CTA Purple Line tracks Thursday after two people attacked him with a brick at the Wilson station in Uptown may have been involved in an earlier robbery a few blocks away.

The 47-year-old man was arguing with another man and a woman at 6:17 a.m. at the station in the 1100 block of West Wilson Avenue, according to Chicago police. During the fight, the man and woman, both 36, punched him and hit him with a brick.

The victim slipped and fell onto the tracks while trying to get away from them, police said.

Red and Purple Line trains were halted as emergency crews worked to remove the man from the tracks, according to police and the CTA. The 47-year-old was taken to Illinois Masonic Medical Center with “a severe head injury.”

Both suspects were arrested a short time later in the 1200 block of West Leland Avenue, according to police. Charges are pending.

Police said the 47-year-old is also “a possible suspect in an earlier robbery” in the 1200 block of West Leland. Investigators are still looking into the details of the alleged robbery.

Red Line trains were moving again with residual delays by 7:14 a.m., the CTA said. Northbound Purple Line trains were rerouted to the Howard-bound Red Line tracks between Belmont and Howard, but normal routing resumed about 8:30 a.m.
