A four-year-old boy died after the off-road bike he was riding hit a lamppost.
The child - named locally as Lennox Railton-Craggs - is thought to have been a passenger on the vehicle, which was involved in a crash in the Eldon Lane area, near Bishop Auckland, County Durham, on Monday afternoon.
Emergency services were called to the scene shortly after 1pm and the child was treated for serious injuries.
