The Ocala Police Department said Cary Lamar Howard, 21, allegedly approached the teenager, who is visiting the United States from Ecuador, during the weekend and showed the boy he was carrying a pistol, the Ocala (Fla.) Star-Banner reported Wednesday.
Police said Howard took the boy's skateboard and demanded cash, but the boy did not have any money. Howard allegedly took the boy's watch instead and fled.
Howard was arrested by an officer who saw he matched the description of the suspect. Howard, who had an outstanding warrant for violation of probation, was identified by the teenager as the person who committed the robbery, the Star-Banner said.
Howard was charged with armed robbery.
