A 10-year-old boy was hit by a van on the busy A23, Brighton Road, in Hooley last night.
Police were called to the scene shortly before 6.30pm after the boy, who was on foot, was knocked down by a blue Ford transit van.
The air ambulance doctor and paramedic were called out 20 minutes later to help treat the boy.
He was taken by land ambulance to St George's Hospital in Tooting with abdominal injuries, which were not believed to either life threatening or life changing.
