South Yorkshire schoolboy Lucas Thorpe was left for fighting for life after being knocked down by a biker - who then fled from the scene.
Lucas, aged eight, was rushed to hospital with a fractured skull, shattered eye socket and broken leg.
He was so badly injured his devastated parents feared their beloved son might not survive.
Five days on, Lucas is sitting up in his hospital bed and able to recall the moments leading up to the hit-and-run which almost took his life.
Yesterday a 20-year-old man was arrested on suspicion of failing to stop at the scene of an accident.
