Why Are Police Searching for Chewbacca?

The police in New Orleans are on the hunt for Chewbacca . . . well, technically, a street performer dressed as Chewbacca!

Police are looking for Chewbacca character because allegedly they got into an argument with someone on Saturday night and wound up STABBING him.  They are circulating a picture of the guy in his full-on Chewbacca costume and hoping it gets them some leads.
