That's put a smile on our face for the first time in many many weeks.. I've been crying so much but it's been tears of joy, our boy would be so proud.

In the past few weeks, detectives from Northamptonshire Police travelled to the US where they interviewed Ms Sacoolas and passed the details of the interview to the Crown Prosecution Service (CPS) for consideration.

No charges against the US suspect have been brought.

Mr Dunn's family travelled to the US last month to put pressure on the administration and President Donald Trump to get justice for their son.

However they were told by Mr Trump that Ms Sacoolas would not return to the UK.

The teenager’s parents said they had refused to meet Ms Sacoolas who was also in the White House as they met Mr Trump, as the meeting would have been "appropriate."
