A teenage camper has captured footage of what he believes is a big cat feeding on a 'dead sheep' in the Peake District, sparking fears that a panther is prowling the British countryside. Josh Williams, 17, had spent the night wild camping with a friend, in the British beauty spot, when they spotted what looked like a panther in the Peak District. He quickly whipped out his mobile phone and was able to capture footage of the close encounter last Monday.
