Police say a man accidentally shot himself in the buttocks at a Nevada movie theater during a showing of “The Bourne Legacy.”

The moviegoer was at the Century 14 theater Tuesday night when a gunshot rang out.

After receiving several calls reporting seven to eight shots, police in Sparks, Nev., dispatched police units as well as fire and medical crews only to find out one shot was fired by accident.

Witnesses inside the theater told officers the gun fell from the man’s pocket as he was adjusting himself in the seat, and it fired when it dropped to the floor, striking him in the buttocks.

The 56-year-old man then reportedly stood up, apologized to those around him and left the theater before police arrived. He checked himself into a nearby VA hospital in Reno, where he was treated for a gunshot wound to his buttocks, according to a police report. His injury is not considered to be life-threatening.

Police say there was no panic in the theater and that only five people reported hearing the gunshot out of the approximately 30 people in the audience. No one else on the scene was injured.

Police said the man has a valid permit to carry a concealed firearm.

The case will be forwarded to the Sparks City Attorneys’ Office when the police investigation is complete.

Sparks City Attorney Chet Adams told NBC News the fact that the man had a concealed weapons permit places a higher standard of responsibility on him.

“You’re supposed to know the laws, you’re supposed to be vigilant in carrying that weapon, and you’re supposed to be trained to use that weapon,” Adams said.

Adams also noted that a revised statute in Nevada would warrant a misdemeanor offense for anyone who negligently discharges or causes to be discharged a firearm in public, and, therefore, he said, “I would certainly be inclined to prosecute.”

“The potential for harm is very strong whenever the discharge of a firearm occurs,” Adams said. “That’s something you can’t ignore. Obviously there was a round chambered and [the man] was in a public place. Those circumstances warrant charges very seriously.”

The incident in Nevada comes less than a month after a mass-shooting inside a movie theater in Aurora, Colo., that left 12 dead and 58 injured.
