Thai police have rescued two baby orang utans in a sting operation after undercover officers arranged to buy the primates over WhatsApp from wildlife traffickers for 700,000 baht (S$28,000).
The endangered animals are less than a year old and are the size of infants.
Police posed as interested buyers and transferred a 100,000 baht down payment to a bank account belonging to a Thai man.
The primates were arranged to be picked up outside a Bangkok supermarket last Wednesday, and were delivered by a city taxi driver.
The driver was arrested but cleared after the authorities determined he was not part of the smuggling gang.
Orang utans are often illegally smuggled throughout South-east Asia.
Counter-trafficking organisation Freeland, which helped with the rescue, said the attempted sale was linked to a "major regional criminal syndicate" involved in the lucrative illegal wildlife trade.
