The police's pursuit of a driver who continued to kill a young woman in an accident was properly performed, a study concluded.
Sarah Giles, 20, died and her boyfriend was seriously injured after the speed driver Branden Daniels lost control of a stolen Audi A3 and crashed into their vehicle in a 30 mph zone.
Daniels, who later admitted to causing death and serious injury by dangerous driving, traveled at speeds of up to 80mph as he plowed into the VW Golf Miss Giles, entering July 29 last year.
Her boyfriend and another man in the Gulf were left in a coma for several days, but Miss Giles later died of her injuries.
Following the accident, a study by the West Midlands Police's exercise of Daniels, Chingford Road, Birmingham, was launched by the Independent Office for Police Conduct (IOPC).
The guard dog concluded the two police boards involved had acted properly.
IOPC Regional Director Derrick Campbell said the persecution was "authorized, proportional and (was) conducted in accordance with local and national policies".
He added: "Police officers drove a safe distance behind the stolen vehicle, and in the end it was the way Audi was driven, which led to such tragic consequences."
Jailing Daniels, 20, for six years and six months at the Birmingham Crown Court last November, a judge told him: "She was intelligent, sweet and generous."
Judge Roderick Henderson added: "She was out with her boyfriend – he was completely harmless.
"Nothing I say or do can put the impurities back."
