41 of the 110 Orang-Utans are missing from Bangkok’s “Safari World” wildlife and amusement park, known for its Orang-Utan kick-boxing shows. The “Safari Park” manager says the creatures died from pneumonia, but Thai police suspect the orang-utans may have been disposed of to avoid DNA testing, to show if they had been smuggled illegally into Thailand.

The Bangkok amusement park has been the target of animal rights campaigners for some time and last week, Thai authorities forced “Safari World” to suspend its Orang-Utan fights while Police investigated the many claims of cruelty and exploitation. Orang-Utans are protected and endangered animals and only found in the wild in the jungles of Malaysia and Indonesia. Forestry officials from Jakarta visited Bangkok last week with smuggling allegations and to press the Thai Government for DNA tests on Safari World’s apes to determine their origin.
