A 16-year-old boy faces criminal charges after a shooting outside a Port St. Lucie movie theater.

Police in Port St. Lucie say a man fired two shots early Tuesday after a dispute arose outside a midnight showing of "The Dark Knight Rises."

Police spokesman Master Sgt. Frank Sabol says the incident was not connected to last week's fatal rampage at a Colorado theater.

Witnesses told local television stations a 16-year-old boy started a fight with a man and his wife. The teen hit and punched the couple, and police said three of the teen's friends joined the fight, surrounding the victims.

The man pulled out a gun and fired two shots over his shoulder, unable to see who or what he was shooting at, police said. One bullet went through a window at the theater, and the other went through the ball cap of the teen holding the victim, police said.

No injuries were reported.

The 16-year-old boy is charged with battery. The man who fired the gun has not been charged.
