PETA protests against controversial Thai rooftop zoo Animal rights campaigners on Monday painted their bodies in bright colours to protest outside a Bangkok mall where the controversial Pata Zoo has been operating on its top floors for over 30 years and known for housing 'Bua Noi' the only gorilla in Thailand. Activists at People for the Ethical Treatment of Animals (PETA) urged the owner to retire dozens of primates and other wild animals and move them to sanctuaries.
