Apenheul Primate Park hoped Sibu would become its breeding male when he arrived two years ago, but orang-utans aren’t his type.

"He chases them, or ignores them, but he doesn’t do what he should do," said a spokeswoman for the park.

Instead, Sibu fancies his female keepers, especially blondes. That, the spokeswoman said, was common for orang-utans but Sibu has a fetish for tattoos, harking back to a heavily tattooed keeper who reared him.

"Orang-utans have special interests in special subjects. Sibu happens to like tattoos," she said.
