A Georgia man has pleaded not guilty to federal charges he carried a stolen gun and ammunition into a Pennsylvania movie theater.

Twenty-one-year-old William Gossett entered the plea at his arraignment Monday before a federal magistrate in Pittsburgh.

Police arrested the Covington, Georgia, man July 23 at the Cinemark Theater in Center Township after he was spotted wearing long-sleeved military fatigues and carrying a large bag into the theater on a 90-degree day. Police searched the bag and found a gun reported stolen in Ohio.

Gossett has an identity theft conviction in Georgia and can't have weapons.

He's charged with illegal possession of a gun and ammo by a felon. He also waived a detention hearing, meaning he'll remain jailed until trial.

Court records don't list a defense attorney.
