A person was released from custody after a man was stabbed Thursday on a CTA Red Line platform in Uptown.
About 3 a.m., a 29-year-old man was on the platform at the Wilson Avenue stop, 1100 W. Wilson Ave., when he started arguing with a 51-year-old man, Chicago police said.
The older man pepper-sprayed him, pulled out a knife and cut the 29-year-old on his left cheek, police said. Officers took the 51-year-old into custody.
The younger man was taken to Weiss Hospital for treatment, police said. He is in good condition.
The 51-year-old was released from custody because the victim declined to press charges, authorities said.
