Shortly after 1 p.m., the man was involved in an argument with someone he knew during a narcotics-related transaction and the other person pulled out a gun and shot him in the left thigh about 1:05 p.m. in the 5400 block of South Wentworth Avenue, according to Chicago police.

He was taken to University of Chicago Medical Center, where he was listed in good condition, police said.

No one was immediately in custody Wednesday afternoon as Area Central detectives investigate.
