Baboons at a safari park in northern England have learnt how to break into car rooftop luggage boxes. In a staged recreation of recent events, Knowsley Safari Park show how the baboons have learnt to open luggage containers on roof racks. Recently, visitors to the park have had their possessions stolen by the anti-social primates. The safari park has now warned visitors that they enter the park at their own risk. (July 21, 2009)
