A rhinoceros embroiled in a love triangle has caused chaos after becoming jealous and rampaging after his cheating mate.
In a case of raging teenage hormones, Satara went on a stampede after he smelt his lover trying to cop off with another beast.
"He got a whiff of his girlfriend from across the road who was hoping to have a night with another bull and I think he got a bit jealous," said Peter Clark, curator of Monarto Zoo in Australia.
The 18-year-old smashed through the steel bars of his pen in search his female and sparked a wide-scale search when staff discovered he was still gone in the morning.
Visitors were kept out of the grounds while keepers used a helicopter to locate the white rhino.
Satara had to be shot with a tranquiliser dart to keep him within the bounds of the open-range site but Mr Clark said the dose didn't stop him.
"There was a whole cocktail of drugs in him but he was moving around so much that I believe his adrenaline levels probably counteracted a lot of the drugs," he said.
But despite the rhino's sex-fuelled rage, Satara was not lucky enough to "have a go", said the zoo's chief executive Chris West.
With Satara fathering two calves already, Mr West said the other male was the preferred breeding option.
"This is boy rivalry, he wants to get to the females first, and if we can't let him in with the females, maybe we'll have to give him a cold shower."
Satara was captured in Kruger National Park, South Africa, and brought to Australia six years ago as part of a captive breeding programme.
