An argument Saturday at a Metter nightclub led to a man's arrest for waving a gun at another and making threats, police said. David T. Hunter, 22, of an undisclosed Metter address, was charged with aggravated assault, possession of a firearm during the commission of a crime, criminal trespass, and marijuana possession, Metter Police Chief Dennis Nelson said. No shots were fired and no one was injured, he said.
