The incident occurred after 10pm on MLK Boulevard at Bayfield Drive.
METRO says a passenger heard the glass shatter and then noticed a window with a bullet hole through it.
"I didn't see it. I didn't see the car or the driver who pulled out the gun," passenger Teron Avery Porter says. "I'm scared. I'm scared."
One passenger claims they were injured by shattered glass, but no other injuries were reported.
METRO police are investigating.
