Two men were shot early Sunday in the Heart of Chicago neighborhood on the Lower West Side.

The men, ages 20 and 22, were driving at 2:41 a.m. in the 2100 block of South Oakley when they heard gunfire and realized they’d both been shot, according to Chicago Police.

The younger man was shot in the arm, while the older man suffered a gunshot wound to the shoulder, police said. Both men, who are documented gang members, were listed in good condition at Mount Sinai Hospital.
