On 10 October 2006, nature conservation officers and Inspector Grobler of SAPS executed a search warrant at Mr Lourens' property in Hammanskraal and seized a baboon and three ant bears. The baboon was placed in the custody of Dr and Mrs Macrae, who operated a game lodge with a zoo license. Mrs Coetzee, a conservation officer, handed over the baboon using a 'Certificate of Handover to Institution', indicating the baboon was being handed to Horseback Africa Zoo. The Macraes understood they would keep the baboon permanently, subject to any trial requirements.
The next day, Mrs Hugo, Assistant Director of the Directorate Nature Conservation, told Mrs Coetzee she had made a mistake and must retrieve the baboon, claiming treasury regulations required it be held at an approved zoo pending trial. On 18 October 2006, conservation officers, a vet, Inspector Grobler and two other police officers went to the Macraes' property to retrieve the baboon. Dr Macrae refused to hand it over, asserting it was now theirs. He was arrested for obstructing justice. Mrs Macrae intervened and was also arrested. Both were charged with defeating/obstructing the administration of justice and theft of the baboon. They were convicted and sentenced (wholly suspended) by the magistrate, and their appeal to the North Gauteng High Court failed.
