A violent incident on a CTA train in Chicago’s Loop neighborhood early Friday morning has left a 32-year-old man in serious condition after a stabbing incident, according to Chicago Police, as confirmed by Chicago Tribune. The man, who has not been identified, was on an Orange Line train around 4:30 a.m. in the 200 block of West Madison Street when two male suspects produced a cutting instrument and stabbed him in the left side; the altercation took place as the city still slumbered in the early hours before the dawn, a moment of vulnerability for a city that prides itself on vigilance. After the incident, the suspects exited the train at the Washington/Wells stop.
