Witnesses told police that the attack happened at 10.30pm when a group of three or four teenagers escorted an injured friend to the emergency room of the hospital.
Another group of some 10 teenagers followed them in and engaged in a brawl in which one of the second group beat the injured teenager with a baseball bat.
One of the teens in the second group then fired a shot into the sky before they all fled by pickup truck and motorcycle. Police later found 12 spent shells of 9mm ammunition at the scene.
The incident frightened doctors, nurses and patients at the hospital.
