Kornell Strenger also faces one felony count of aggravated battery, Chicago police said. Authorities say he is a previously convicted gun offender and was sentenced to four years in 2015.

The shooting happened at the Jackson Street subway station, on the northbound platform. Police say the gunman fired at his victim, striking him in the shoulder and foot, in connection with a verbal altercation that had occurred earlier.

Police had circulated surveillance photos of the gunman and announced earlier this week they had a person of interest in custody.

The victim was taken to Northwestern Memorial Hospital.
