Police are looking for a man who fired a gun on a CTA platform in the Loop on Saturday morning. No injuries were reported in the incident, but officers did find shell casings at the scene.
Officers responded to the Clark-Lake Blue Line platform around 11:17 a.m. after callers reported hearing shots fired and a man with a gun, said Officer Steve Rusanov, a CPD spokesperson.
A witness told officers that two men were arguing on the platform at 117 West Lake before one of them pulled out a rifle or large handgun and began firing down the platform. The gunman then escaped by boarding a Blue Line train.
Illinois State Police troopers who patrol the adjacent Thompson Center found three shell casings on the platform. Chicago police officers recovered them for analysis.
Saturday’s gunfire was the second major incident of the week at the Clark-Lake station, which serves as a transfer point between nearly all of the CTA’s train lines.
On Wednesday evening, a man stabbed a 30-year-old man in the back during an argument on the outdoor platform that serves Orange Line and other trains around 7:35 p.m. The 30-year-old then grabbed the assailant’s knife away and stabbed the attacker in the neck, killing him, police said.
The 30-year-old was taken to Rush Hospital in good condition. Authorities have not identified the deceased man or released his age.
