A MOTHER has issued a heart-felt plea for a witness to a collision that left her nine-year-old son with a broken leg to come forward.

Sporty youngster Henry Brydon has been left with potentially life-changing injuries following the incident in Dorchester’s Great Western Road.

Henry’s mum Sophie Freeman is urging a stranger who helped the boy at the scene and saw what happened to contact the police, otherwise she fears any prosecution against the driver involved will be dropped.

She described the mystery Good Samaritan as ‘our last hope’.

Miss Freeman was in the county town with Henry, his three-year-old brother Arthur and their pet dog following a trip to the dentist and the vets.

They were getting back into the car at around 11.30am when the incident occurred.

Miss Freeman, 33, from Piddletrenthide, said: “Henry was standing next to me at the rear of my car on the pavement side, I unlocked the car and Arthur climbed in, the next second I turned back to see Henry screaming.

“He was lying on the ground with his body on the pavement and the bottom of his legs in the parking bay.”

She said a man came past to help and told them he had seen the collision, before he set off down the road towards Trinity Street to flag down the driver.

Miss Freeman said: “When I next looked up he was gone.”

Miss Freeman is now desperately appealing for the stranger to contact the police as she has been told they cannot proceed with a prosecution without his witness statement.

She said: “I am just trying to track this man down as he is our last hope.

“He saw it happen, he chased her down the street and he was just genuinely lovely. If nothing else it would just be nice to say thank you.

“Ideally we would like him to go to the police and tell them what he saw.”

Henry, a keen Rugby player with Sherborne Rugby Club, was taken to hospital and had to have a full leg cast as two bones in his leg were broken.

Early X-rays have shown potential bone displacement that could leave his leg permanently weak.

Miss Freeman has been back to Great Western Road to put posters in the shop windows appealing for witnesses to the incident and says the incident has had a ‘devastating’ effect on her boy.

Language teacher Miss Freeman, who had to turn down a job offer to look after her son, said: “Rugby is something he loves and he’s so active.

“If the leg is permanently weak he might end up playing one season but if he does anything to the leg he won’t be able to play again.”

She added: “It’s been devastating for Henry, and he hasn’t been back to school since. The impact on us has been huge. If Henry’s leg doesn’t heal, that’s it for his rugby.”
