A six-year-old boy is fighting for his life after a quad bike he was a passenger on smashed into a motorbike in a head-on horror crash.
The youngster was thought to be riding with his dad when their off-road motorbike collided with another Wintersett Nature Reserve in Wakefield, West Yorks.
Police said he suffered serious head injuries, which were described as 'life-threatening' and issued an appeal for witnesses.
West Yorkshire Police said the collision happened at around 1pm on Sunday afternoon.
A spokesman said: "A quad bike travelling along a concrete footpath through the nature reserve, from the direction of Santingley Lane, was in collision with an off-road motorbike which was travelling in the opposite direction.
"The six-year-old boy, who was a passenger on the quad bike, suffered serious head injuries in the collision."
