Flagstaff police are stepping up patrols in the northern Arizona city's downtown because of rowdy behavior associated with the bar scene.
Deputy Chief Walt Miller says police have been dealing with intoxicated people who get into fights and other misbehavior.
The number of officers patrolling downtown at bar closing time has been doubled to six from three in the past six months.
The Arizona Daily Sun reports that police are stepping in to immediately break up fights and urging bars to banish troublemakers from the nightspots.
