EXTRADITION REQUEST DENIED: Harry Dunn Family distraught and angry but not surprised over decision.

An extradition request for the US woman charged with causing the death of teenage motorcyclist Harry Dunn has been turned down by secretary of state Mike Pompeo, the family spokesman has said.

The 19-year-old’s parents were informed of Pompeo’s decision in a phone call with their constituency MP Andrea Leadsom on Thursday. A spokeswoman for the Home Office said it was a “denial of justice, we are disappointed in this decision, “We are urgently considering our options.”

Dunn was killed when his motorbike crashed into a car outside a US military base in Northamptonshire on 27 August 2019. Anne Sacoolas, 42, was charged with causing his death by dangerous driving in December. She was granted diplomatic immunity and was able to return to the US, sparking an international controversy.

The case has been a thorn in London’s close relations with Washington, stirring up debates over the limits of diplomatic immunity in cases unrelated to national security. A family spokesman, Radd Seiger, said Dunn’s parents “were not at all surprised”.

“This is a lawless, corrupt administration that appears intent on attacking even its closest international ally,” he said. “If Trump and Pompeo think this is an end to the matter, they have another think coming to them.”

The family would meet with the government to discuss the next steps but said “the fight goes on” for justice for their son. Seiger told BBC Radio 5 that he understood no reason had been given for Washington’s decision.

 Lawyers acting on behalf of the Dunn family have said it is the first time in the 100-year history of the extradition treaty that such a request had been turned down by the US.

But the US state department said Sacoolas had immunity from criminal jurisdiction during her stay in the UK.
