Unwanted Roommate

Hopefully this isn't a new trend amongst muggers. The NY Post reports that after a 25-year-old man mugged a Newkirk Avenue (off Bedford Avenue) resident inside his apartment building, he decided to set up camp and live there for more than a day, even fooling the locksmith into thinking it was his apartment after the real resident called to have the locks changed! Cops eventually intervened, but, shouldn't that have taken a lot less time?
