Rival jewelers in Manhattan’s Diamond District erupted into a wild, caught-on-camera brawl Friday afternoon in front of stunned shoppers – landing two business owners in cuffs and another in the hospital. George Akay, 46, and his brother Freddy, 42, were both busted for allegedly pummeling competing jeweler, TraxNYC owner Maksud Agadjani, during the violent clash inside their shared business space on West 47th Street, police said.
