Joshua Hoyle was critically injured when a car driven by his father, Andy Hoyle, was involved in a collision on Wednesday, August 18.
He sadly died from his injuries on Friday, August 27.
Joshua’s mother, Trudie Hoyle (pictured), said: “Joshua was our loving and energetic boy and the centre of both mine and Andy’s world. To have lost both of them in this way is absolutely devastating.
“As a family we will never stop loving and missing them, and would ask to be allowed to grieve privately while we come to terms with this tragedy.”
A 76-year-old man has been arrested on suspicion of causing death by dangerous driving and for failing to stop after a road accident. He has been released under investigation while enquiries continue.
Police investigating the collision, which occurred shortly after 11am, continue to appeal for any witnesses to come forward.
They would particularly like to hear from anyone who may have captured any dash cam footage from the area around that time.
