The suspects were caught on camera last Friday in a store on Port Richmond Avenue in Staten Island.
Police say the suspects enter the locations, produce a firearm, tie up the store clerks and flee on foot with money and cell phones. At least four of the incidents occurred at Metro PCS stores.
They have struck at least five times, beginning on August 15.
Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS.
