A policeman in Sussex suffered four broken ribs and a punctured lung after being attacked by a herd of cows. He was walking his dog on the South Downs when a cow butted him in the back pushing him to the ground. The other cows in the herd also started to attack him. Mr Poole escaped when the cows were distracted by his dog running away. The RSPCA warned that although cow attacks are rare, they can become aggressive when protecting their young.
