Members of the public intervened to protect the swan
A woman who rescued a swan from a busy Surrey road only to see a car then mount the grass verge and run over the bird.
The woman contacted the Swan Sanctuary at Shepperton on Friday after finding the injured animal in Fernbank Avenue, Walton-on-Thames.
While waiting for help to arrive, the woman said a vehicle, possibly a Land Rover, left the road, hitting the swan.
It was in a serious condition with a head injury and a broken leg.
The incident took place at about 0945 GMT.
A Surrey Police spokesman said members of the public intervened to help the swan and the vehicle drove away from the scene "at speed".
A spokesman for the Swan Sanctuary said: "As soon as his condition is stable the swan will have to undergo surgery.
"At the present time the swan's condition is very serious."
