A farmer in Devon has been forced to slaughter half his herd of Heck cows after they repeatedly tried to attack his farm workers.

Farmer Derek Gow said that the Heck cow descended from cattle specifically bred by Nazi scientists between the world wars. The Heck cow was renowned for its fearsome horns and extremely aggressive nature.

Fearing for his life, Mr Gow said that he had no choice but to destroy 20 of his most aggressive cattle.
