Elusive street artist Banksy claims another animal-themed mural, this time of a gorilla releasing animals on one of the shutters of London Zoo. London Zoo’s Karl Penman says the mural is 'an absolute shock and surprise,' adding that 'if it is the full stop, what a great full stop to end on.' The gorilla is the ninth of what some are dubbing Banksy’s London safari. IMAGES AND SOUNDBITES
