While Melbourne has a policy of encouraging street art, it also has a problem with gangs
tagging walls and public property. Melbourne's deputy
Lord Mayor Susan Riley sent cleaners to Hosier Lane after residents complained about squalid conditions in the alley. The cleaners were instructed to tidy up the rat-infested garbage and remove all graffiti from unapproved street art sites. Leaving alone the approved sites, the cleaners painted over
Parachuting Rat, by then thought to be the only remaining work by Banksy on public view in the city, with a thick layer of battleship-grey paint. Challenged at the time by a local resident, the cleaners replied 'we are just doing what we're told'. Another was destroyed in May 2012 by builders working on plumbing. The building owner, who knows Banksy through a New York contact, said that he laughed at the fact that "TV Cameras took an interest in his work" in an email she sent them about the incident. ==Reaction==
