Federal authorities seized more than 1,000 firearms from the unincorporated east Mesa home of a man they accuse of being an unlicensed gun dealer who unlawfully sold firearms at area gun shows.

About two dozen Maricopa County Sheriff's deputies and Bureau of Alcohol, Tobacco, Firearms and Explosives agents clad in bulletproof vests and assault rifles surrounded the home of Robert B. and Lois Daly before 6 a.m. Monday.
