The Independent Police Complaints Commission has been called in after the death of Bilal Raffey Khizar on a crossing near Asda on Rooley Lane in Bradford. An investigator is undertaking an independent assessment into the police role into Bilal's death.
The police had pulled over a Seat Ibiza and as the officers approached, the car made off at speed, and hit the 12-year-old. The car did not stop and continued onto the Chain Bar roundabout, where it collided with two other vehicles. The car was later found on Westfield Lane, in the Wyke area of the city.
Two people have been arrested and police are still appealing for witnesses.
Bradford Academy, which Bilal attended, has released a statement about the "unique and hugely respected" pupil.
Gareth Dawkins, Executive Principal of Bradford Academy, said: "The tragic loss of Bilal Khizar on Saturday night is a devastating blow for everyone connected with this beautiful and unique boy. Everyone at Bradford Academy, and indeed everyone in the community we serve, is grieving for Bilal, and for his family and his friends.
"Everyone at Bradford Academy - pupils, staff and parents - are united in grief over the tragic event this weekend, and we will be doing our utmost to console Bilal's two other brothers Aafacq (Year 12) and Zain (Year 10) and his sister Neha (Year 1) who are pupils here, as well as the all the other children and staff who knew, loved and respected Bilal.
"It is exceedingly difficult for our pupils to understand that Bilal was taken away from them while doing an everyday, routine task.
"He was a super and capable young lad, his future was wide open for him. He did what he should, crossing a road where he should. His tragic death will touch everyone in the community.
"I promise that Bradford Academy will do whatever we can for the family. But I also promise we will press for - and achieve - greater road safety measures in the area around our school. Although this happened outside of school and school hours, the impact will be felt in our school for years to come."
