A suspect granted diplomatic immunity in the case of the death of Harry Dunn will reportedly not return to the UK (Family handout)

Notes held by Donald Trump appear to show that the US has no intention of sending a suspect granted diplomatic immunity in the case of a teen killed in a road crash back to the UK.

Harry Dunn, 19, died when his motorbike crashed into a car outside an RAF base on August 27.

President Trump spoke of the case yesterday after a conversation with Boris Johnson and said his administration would speak to the driver, while also saying driving the wrong way “happens”.

After addressing reporters on the case at the White House, a photograph has since emerged which showed a note held by Trump that reads: "(If raised) Note, as Secretary Pompeo told Foreign Secretary Raab, that the spouse of the US government employee will not return to the United Kingdom.”

Since the photograph has surfaced, Mr Dunn's mother Charlotte Charles has blasted the President, suggesting his approach to the case has been "beyond any realm of human thinking”.

The suspect, 42-year-old Anne Sacoolas, reportedly married to a US intelligence official, was granted diplomatic immunity following the crash.

The car which crashed into Mr Dunn was thought to have been driving on the wrong side of the road after leaving RAF Croughton in Northamptonshire, a military base used by the US Air Force.

The teenager's family met with the Foreign Secretary on Wednesday but said they left the meeting feeling "angry" and "disappointed", with Ms Charles later saying it seemed like a "publicity stunt" and that they felt "patronised" by Dominic Raab.

Mr Raab met Mr Dunn's mother and father Tim Dunn on Wednesday afternoon after having talks with US Ambassador Woody Johnson on Tuesday.

Speaking to Sky News about the photograph of notes held by Trump which seemed to suggest Mrs Sacoolas would not be returning to the UK, Ms Charles said: "I'm just disgusted.

"I don't see the point in Boris Johnson talking to President Trump, or President Trump even taking a call from Boris Johnson.

"If he'd already made his decision that if it were to be asked and if it were to be raised, the answer was already going to be no.

"It's just beyond any realm of any human thinking.”

Commenting on what she would say to Trump about the case, Mr Dunn's mother told Sky News: "He must know exactly where she is.

"He must know where she, the kids, the husband are - whether they are being hidden or they've just run away - one way or another he must know exactly where they are.

"I would obviously urge him to still put her on the plane to come back, face our justice system here, face us, talk to us, everything we have been saying for the past five days.

"We will keep the pressure on - we still don't understand, none of us as a family, everyone around the world that keeps contacting us.”
