Thai police rescued two baby orang-utans in a sting operation after undercover officers arranged to buy the primates over a mobile phone messaging app from wildlife traffickers for nearly US$20,000, officials said. An anonymous tip alerted police to an online advertisement for the endangered animals, who are less than one year old and the size of infants. Police then posed as interested buyers and contacted the seller over WhatsApp, according to deputy national park director Adisorn Noochdumrong. “They agreed to buy the two orang-utans for 700,000 baht (US$19,400) and transferred a 100,000 baht down payment to a bank account that belongs to a Thai man,” he said. The undercover officers arranged to pick up the baby apes outside a Bangkok supermarket on December 21, where the orange-furred creatures were delivered by a city taxi driver.

Orang-utans are native to Malaysia and Indonesia but they are often illegally smuggled throughout Southeast Asia, either for private zoos or pets. Thailand has long served as a transit hub for contraband wildlife products bound for major markets like Vietnam and China. Counter-trafficking organisation Freeland, which assisted with the orang-utan rescue, said the attempted sale was linked to a “major regional criminal syndicate” involved in the lucrative illegal wildlife trade. Social media has become an integral tool for such gangs to set up sales, said Matthew Pritchett from Freeland. “This case is one link in a much larger chain,” he added.
