A man was stabbed during a fight on a Red Line train late Tuesday morning near the Chicago Avenue station — the fifth attack on the CTA in a week.
A witness told officers that two people began arguing and then fighting on a train around 11:45 a.m., police said.
One of them took out a knife and stabbed the man, 40, in his abdomen, police said. The man was taken from the station at 800 N. State St. and brought to Northwestern Memorial Hospital, where his condition stabilized.
Police said no one was in custody.
