The UK and the US are reported embroiled in a diplomatic row over Northamptonshire teenager Harry Dunn.
Washington officials were “furious” to learn UK police had put an international wanted notice out for Ms Sacoolas, 42, The Mail on Sunday said.
The wife of a US intelligence official, she claimed diplomatic immunity after the crash and was able to return to her home country.
However she was charged with causing death by dangerous driving in December, but an extradition request submitted by the Home Office was rejected by US Secretary of State Mike Pompeo in January, a decision the State Department has since described as “final”.
The Mail says bilateral tensions have erupted after British police enacted an Interpol Red Diffusion Notice, which was sent to certain countries including Canada, seeking Sacoolas’s arrest if she left the United States.
Washington was reportedly not notified about the move in hope Sacoolas would leave the country and be arrested.
US officials were said to have been furious on learning of the notice’s existence and confronted British counterparts, prompting crisis talks last Thursday involving Prime Minister Boris Johnson, Foreign Secretary Dominic Raab, and Home Secretary Priti Patel.
The Mail said Northamptonshire Police are being blamed by the Government for news of the notice emerging.
