Beaufort West - A helicopter is being used to try and find an elusive lion which escaped from the Karoo National Park near Beaufort West and is heading for the hills. Using an electronic collar, the lion was last tracked 20km south-west of the park. It is understood that the cat is a serial escape artist, having left the park last year after finding a hole under the perimeter fence. SANParks spokesperson Reynold Thakuli said on Tuesday that the lion was “very much still on the loose”. “We have a 14-man search team, including a veterinary surgeon, and we are also going to be using a chopper because it looks like it is heading into the hills where the terrain is rough and mountainous and it is difficult to track on foot,” he said. “As soon as they get close to the lion it moves, so we will take to the air this morning.”Thakuli said the lion apparently killed a cow during the night, on a farm which neighbours the park.
