This incident isn't the first of its kind.
Two years ago, authorities held a "super-hero summit" designed to reduce tensions among the impersonators and performers.
That meeting was prompted in part by an incident in which a street performer dressed in a Star Wars wookiee costume allegedly head-butted a tour guide who complained about his treatment of Japanese tourists.
In other incidents, actors dressed as the superhero Mr. Incredible, Elmo the Muppet and the dark-hooded character from the movie "Scream" were arrested for being too aggressive with tourists.
A man dressed as the horror film character Freddie Krueger was also taken into custody for allegedly stabbing someone. No charges were ever filed.
