A 77-year-old great-grandmother from Norwich suffered a fractured foot after she was sent flying by a hit-and-run driver - on a mobility scooter.

Mother-of-five Pauline Potter from West Earlham has been in agony since the crash outside Mousehold Garden Centre on Saturday afternoon.

Her daughter Denise Maskell, who was with her and reported the incident to police, said she is horrified by what happened and said the crash has left her mum unable to walk or sleep properly.

Ms Maskell, a mother of three, from Portway Place, off Old Palace Road, said her mother is too tired to talk about the ordeal but she said she is 'so angry' about what has happened.

She said: 'It's disgusting what she's now having to go through. She has a lot of health problems and just didn't need this.'

The crash happened at about 3pm when they were returning to the car on Corbet Avenue behind the Mousehold Lane-based garden centre where Ms Maskell had taken her mother to buy some plants.

She said: 'We'd had a nice day out. We'd put her plants down ready to open the car door and I heard her scream out and as I turned round this mobility scooter had ploughed into her. She went over the top.'

Ms Maskell said she tried to pick her mother - who has 15 great-grandchildren and 16 grandchildren - up from the floor - to avoid her being struck by any passing cars - but was struggling until she was helped by four women who came to her aid.

She said: 'She couldn't stand up. Four people came to help me get her up and I wanted to thank them.'

Initially Ms Maskell took her mother home but she was unable to walk and they called for an ambulance which took Mrs Potter to the Norfolk and Norwich for an X-ray which confirmed she had broken a foot.

Her foot had to be put in a temporary plaster following the crash but she has now been given a boot to wear to try and help it heal.

Ms Maskell, a communicator guide who helps deaf and blind people and works with Norfolk County Council's sensory support unit as well as Dereham-based charity Sense, said her mother has been in agony and still struggles to get up of the sofa or sleep.

She is upset that the person responsible failed to stop after the crash. She said: 'I think it's disgusting. It was a big scooter. He or she knew they hit my mother and they just carried on going and that's what makes me really angry.

'They were coming up behind us and so saw my mother had a stick. They just came from nowhere and my mum flew up in the air.'

Ms Maskell urged anyone with information about the incident to contact police who confirmed they have received a report about the incident.

Since 2009 Norfolk police have run awareness courses for mobility scooter users aimed at cutting down on the number of accidents involving them.

Mannequin dolls, simulating pedestrians on the high street, are among the obstacles drivers have to negotiate as part of the course which also features a Safe Scoot film.

Anyone with information should call police on 101.
