Watch as a teenager dressed in a clown mask robs this Domino's pizza worker using what looks like a gun. This is surveillance video from inside the fast food shop in Phoenix, Arizona. Cops say two 17-year-old suspects have been arrested in connection with the crime here and a similar incident at a Taco Bell within an hour of each other. Police say the teen hiding behind the mask was charged with three armed robberies. The other teen, they say, acted as the getaway driver.
