The Independent Office for Police Conduct (IOPC) investigation concerning the deaths of four men in Bradford following a West Yorkshire Police pursuit is complete.
Murtza Chaudhry, aged 21, Arbaaz Hussain also aged 21, Zeeshan Khalid, aged 20 and Tayyab Siddique, aged 22 all died when their car hit a tree on Toller Lane in the early hours of 2 August 2018.
Before the crash, officers were concerned about the manner in which the car was being driven on Stony Lane.
A short pursuit began after they failed to stop for officers.
The IOPC say their report is now with West Yorkshire Police, awaiting the conclusion of any inquest proceedings before they can consider publishing their findings.
