A 78 year-old woman was knocked to the floor by a car which then drove off, police say.

The pensioner, who survived and was not seriously injured, was struck by a passing vehicle in Crown Road, Marlow, on Saturday, officers revealed this morning.

It happened about 9pm.

Police said the car, a black Audi A3 S-line or Quattro, possibly with a 54 plate, drove off from the scene without stopping.

The victim sustained bruising to her elbow and wrist.

During the collision, the glass in the wing-mirror on the passenger’s side of the car was broken.

Anyone who witnessed the collision, or has seen a black Audi A3 with a broken wing-mirror should contact PC James Fergusson via the 24-hour Police Enquiry Centre on 101.
