PORT ST. LUCIE, Fla. (AP) -- Gunfire erupted outside a Florida screening of the latest Batman movie, but no injuries were reported.

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

Treasure Coast Newspapers reports a 16-year-old boy was narrowly missed by one of the bullets.

The gunman's identity was not immediately released.
