Police in Christchurch are trying to find the rider of a mobility scooter, who knocked down a woman and didn't stop.

The 63 year old sustained minor head and leg injuries after being hit outside the Zoo jewellery store on the High Street, just before 2 P-M back on Monday April the 30th.

Officers say another woman - about 50 with long blonde hair and a light-coloured jacket on - carried on towards Sopers Lane.
