LONDON (AP) - British police are investigating a fox attack on a 4-week-old baby in his home in London. Scotland Yard said the boy was admitted to a hospital Wednesday after the fox injured his hand. British media including the BBC and the Press Association reported Saturday that the fox bit one of the baby's fingers, and that the boy was recovering after surgery. It was not clear how the fox entered the home. Mayor Boris Johnson is calling for more to be done to tackle what he called the "growing problem of urban foxes." Some have called for a cull of the animals, which are a common sight at night in quieter areas of the capital.
