A man has been arrested after a five-year-old girl was knocked down while riding her scooter on the pavement in a terrifying hit-and-run.

Casey Wilson was riding home from the park when she was knocked down by a speeding BMW in Grangetown, Cardiff.

The driver lost control as he turned the car left at speed and mounted the pavement in front of them.

Fortunately, the youngster escaped with only minor injuries but was left badly shaken by the ordeal.

Police shared footage of the smash and appealed for witnesses but have since arrested a 34-year-old man.

This is a young girl walking along the pavement before she was knocked off her scooter as a hit-and-run driver allegedly mounted the pavement 

Casey Wilson, 5, can be seen riding her scooter along a seemingly quiet road 

Casey's mum Rachel Bancroft said: 'It all happened so quickly and I just thought she was dead. I thought she had been killed in front of me.

'People out there know something. It is very lucky that my little girl was killed and someone needs to come forward with information. Next time it might be a fatality.'

A spokeswoman for South Wales Police said: 'A man has been arrested in connection with a road traffic collision which happened on Sloper Road, Cardiff.

'A 34-year-old man from Grangetown has been arrested on suspicion of dangerous driving, failing to stop a vehicle, and failing to report an accident involving a vehicle which he was driving.

'A car suspected of being involved has been seized and continues to be forensically examined.

'The girl's family has been updated.

'Amazingly the little girl received only minor injuries, but the incident, which happened at around 5.50pm on Sunday, March 24, was understandably very frightening for her and her family.

'The matter is being taken seriously and the investigation is progressing effectively.

'The arrested man is on conditional bail pending further enquiries.

'If you witnessed this collision or the vehicle involved, please contact us.'

Footage of the incident shows the five-year-old riding a scooter along the pavement next to a seemingly quiet road. 

Casey's mum Rachel Bancroft said: 'It all happened so quickly and I just thought she was dead' 

Casey's mother Rachel Bancroft then rushes to help the five-year-old, as do other pedestrians.

Miraculously, the girl was able to escape the incident with only minor injuries. 

Casey's mother said that the hit-and-run had left the young girl terrified of moving vehicles.

She said: 'We were out the other day and a motorbike went past and the noise made Casey jump out of skin.

'Another time we were walking and a bus went past and she was trying to get on the inside and was shaking. 

'She is still terrified, and I keep replaying the moment in my head. It was like something out of a film.'

A police spokeswoman: 'South Wales Police is continuing to investigate a collision which happened on Sloper Road, Cardiff.

'Amazingly the little girl received only minor injuries, but the incident was understandably very frightening for her and her family.

'Officers are appealing for the driver or anyone with information to please contact South Wales Police.

'It happened at around 5.50pm on Sunday, March 24, during the school Easter holidays.'
