The US has turned down an extradition request for an American woman charged with causing the death of teenage motorcyclist Harry Dunn, a family spokesperson has said.
Radd Seiger said the 19-year-old’s family were informed of US secretary of state Mike Pompeo’s decision during a phone call with their constituency MP Andrea Leadsom.
Ms Leadsom is due to meet the US ambassador Woody Johnson in London on Friday to discuss the case.
In a statement, a spokeswoman for the Home Office said: "We are disappointed in this decision, which appears to be a denial of justice.
"We are urgently considering our options."
Dunn was killed when his motorbike crashed into a car outside a RAF Croughton, a US military base in Northamptonshire, on 27 August last year.
Anne Sacoolas, 42, was charged with causing his death by dangerous driving by the Crown Prosecution Service in December.
Ms Sacoolas was granted diplomatic immunity following the crash and was able to return to her home country, sparking an international controversy.
Boris Johnson previously said the chance of the suspect ever returning to the UK was very low.
Dunn’s family said they would react fully to the news on Friday morning, but said “the fight goes on” for justice for their son.
