According to WGN News, the 25-year-old victim says he was heading southbound on the train when he was stabbed in the stomach by a man. The attacker demanded his wallet, but the 25-year-old man did not comply. The attacker then ran off the train, and someone on the same train car pulled the emergency alarm.
The alarm prompted the train operator to halt the train at the Argyle stop, and walk back to the fourth train car to check on the victim. Paramedics arrived shortly after, and the man was transported to the hospital in serious to critical condition. No arrests have been made.
