37-year-old Scott Smith was arrested in Cleveland, Ohio, after entering a movie theatre showing the violent film "The Dark Knight Rises" with a gun (9mm Glock), ammunition and four knives. An off duty police officer doing security at the cinema became suspicious when Smith brought a large bag into the venue and sat with his back to the wall at the very back of the cinema.

He was arrested shortly after and police discovered Smith was not licensed to carry a gun. A search of his home revealed more guns, ammunition, gas masks and bullet proof vests. This marks the third security alert that has occurred in America at a showing of the "Dark Knight Rises." Previously, a fight and stampede broke out in one theatre and threats were exchanged, while in another incident, shots were fired outside the theatre. In Mexico, a masked gunman robbed two theatres showing "The Dark Knight Rises."
