Alex Batty has reportedly touched down in the UK for the first time in six years after the missing teen flew back from Toulouse.
The 17-year-old, who was aged 11 when he went missing, landed on Saturday night and Greater Manchester Police is set to hold a press conference. He is also set to be reunited with his grandmother who he has already reached out to.
Alex disappeared six years ago while on holiday in Spain with his mother Melanie Batty and his grandfather David Batty.
It is thought the three moved around from country to country before David died six months ago. Alex is said to have fled from his mother when she announced she would be travelling to Finland - where she is likely to have now arrived.
Greater Manchester Police has said it will not comment "at this time" on what Alex was doing while abroad, as the force has not yet received a statement from the teenager.
Assistant chief constable Matt Boyle told reporters: "We are aware the French authorities disclosed detailed information yesterday during their press conference relating to what Alex may have been doing and where he has been over his years missing.
"Greater Manchester Police are yet to obtain any formal statement from Alex and therefore we cannot comment at this time."
He walked for four days and nights in the Pyrenees mountains and was found by chiropody student Fabien Accidini while walking alone near Toulouse in the early hours of Wednesday.
His grandmother and legal guardian Susan Caruana previously said she "can't wait" to see him when he returns.
"I cannot begin to express my relief and happiness that Alex has been found safe and well.
"I spoke with him last night and it was so good to hear his voice and see his face again. I can't wait to see him when we're reunited.
"The main thing is that he's safe, after what would be an overwhelming experience for anyone, not least a child.”
She had told the press that the three had been living an alternative lifestyle, travelling between Spain, Morocco, and France in their years of exile.
Alex was described as "tired" but "in good health" after being checked over by French officials and seemed "intelligent" even though he had not attended school for six years.
Greater Manchester Police said Alex had been "well cared for" by the French authorities and had a video call with his grandmother on Thursday.
