A fresh appeal has been made following yesterday's crash in Devizes.
Police have confirmed that the teenager involved is 13-years-old.
They say the boy had exited a bus and was then involved in a collision with a silver van while crossing the road.
He was airlifted to Bristol Children’s Hospital with serious injuries, but these are not believed to be life-threatening. He is currently in a stable condition.
The male driver of the van remained at the scene and no arrests have been made.
The road was closed until around 10pm last night so emergency services could deal with the incident and officers could carry out collision investigation work.
PC Pete Fennell, from Wiltshire Police’s Collision Investigation Unit, said: “We know the road would have been busy at the time of the collision so we would urge any witnesses, including anyone who may have dash cam footage which could assist our enquiries, to come forward.
“Please call the unit on 101, quoting reference 54210047359.”
An ambulance spokesman added: "We were called on Tuesday 18 May about a collision between a pedestrian and a vehicle on Horton Road, Devizes.
"We treated a young male patient at the scene, and he was conveyed to hospital by air ambulance with a serious leg injury."
