Three employees of South Africa’s premier national park have been arrested for alleged rhino poaching. They’ll appear next week after a joint operation by National Parks Board and police operatives found them in possession of hunting rifles, ammunition and poaching equipment. Most of the nearly 800 rhino poached in South Africa this year have been in the Kruger National Park, a game reserve the size of Israel on South Africa’s north eastern border with Mozambique and Zimbabwe. The arrest of the three employees follows discovery of a rhino carcass. It follows the arrest last week of ten members of a syndicate believed to have poached 84 rhino between 2008 and 2012. The men are being held in custody. Chief executive of the South African branch of the World Wildlife Fund Morne du Plessis told a press conference marking World Rhino Day that to curb poaching it’s vital to target the behaviour of horn users. Most of the horn sourced in South Africa ends up in Vietnam. Once it was used for medicinal purpose. Rhino horn, which is made from the same substance as human finger nails was mistakenly believed to have properties for curing cancer. Now, because if its value, it is being bought by younger customers who hold it as a status symbol or give it as a corporate gift.
