According to The New York Times (2017-11-04) (no paywall page):
Several years ago, the Indonesian police rescued a female orangutan who had been shaved and was being used as a prostitute at a brothel.
No further detail is furnished. No source is given for the above information, though as the article is written, I infer that this information was from one "Daniel Stiles, a self-styled ape detective who lives in Kenya".
So is this claim true or false? Did any human being ever pay for sex with an orangutan in Indonesia?
