Puzzled police want to piece together exactly how a frail OAP suffered a head injury which left her needing treatment in hospital.
Investigators are seeking witnesses to the incident in which the elderly woman was injured in a Rose Green street.
Police say at 8.45am on Saturday (29 April) the 90-year old local woman was outside the Post Office in Rose Green Road, Bognor, when she fell to the ground and sustained the head injury for which she was treated at St Richards Hospital in Chichester.
PC Jon Bennion-Jones of the Surrey and Sussex Road Policing Unit said: “It is not currently clear what happened but we are investigating the possibility that she may have been struck by a car.
“If you were in the area and saw what happened, please contact us via [email protected] quoting serial 0360 of 29/04. You can also report online here or call 101.”
