Maricopa County prosecutors say 41-year-old Tony Tucker was sentenced Friday.
Tucker was one of three men police dubbed the "Fast Food Bandits" who allegedly robbed seven Subway and McDonald's restaurants in Phoenix and Tempe from September to November in 2011.
Police say Tucker was involved in all seven robberies and forced one restaurant employee to disrobe and fired a gun twice in the direction of a customer.
Tucker was arrested in January 2012. He was charged with six armed-robbery counts, 11 kidnapping counts, 12 aggravated-assault counts, one count of attempted sexual assault, three counts of unlawful discharge and one of attempted armed robbery.
