Two people have been arrested after a 12-year-old boy died in a hit-and-run incident involving a car that had just been stopped by police.
The boy was on a crossing on Rooley Lane, in Bradford, West Yorkshire, when he was hit by the red Seat Ibiza at around 7pm on Saturday.
The collision happened as the car made off at speed after being stopped by police for a check, West Yorkshire Police said.
A force spokesman said a marked police car stopped the Seat Ibiza in a lay-by on Rooley Lane for a check.
As officers got out of their car to approach the vehicle, it made off at speed along the road before colliding with the boy on a crossing close to the Asda store.
The spokesman said: "He tragically died of his injuries."
The car did not stop but continued to the Chain Bar roundabout on the M606, where it was in collision with two other vehicles. It was later found on Westfield Lane, in the Wyke area of Bradford.
Two people were arrested overnight as a result of police inquiries, which were said to be at a very early stage.
Detective Superintendent Mark Ridley, who is leading the investigation for West Yorkshire Police, said: "This is a tragedy for the family and they are absolutely devastated. Specially trained officers are currently working with them.
"I am appealing directly to anyone who saw the vehicle being driven or the incident to get in contact. I need the community to come forward and tell me what has happened and what they have seen to help bring justice to the family."
