Wild Horses
Podagros (the fast), Lampon (the shining), Xanthos (the blond) and Deinos (the terrible), known as the Mares of Diomedes raced through the streets of London. Fire streamed from their mouths and nostrils as they ran.

The unlucky citizen or tourist who couldn't get out of the way fast enough were either burned, or on the rare occasion ran down and eaten by the flesh eating horses. Police tried to set up barricades to stop them, but the wild horses would not be stopped or contained.
