Esme Smith, the teenager who was found safe and well after an 11-day search, has so far refused to talk to police and hasn't yet returned home to her parents.
Esme, 14, has not answered questions as to her whereabouts or who she was with after she disappeared after boarding a train, sparking a nationwide appeal.
A Surrey Police spokesman said she has also not returned home to her parents Nato commander Mark, 50, and Dinah, 39.
The force has said there have been no allegations of any criminal activity and there is no evidence Esme has been groomed.
Esme, from Farnham, Surrey, walked into a North London police station earlier this weeek 11 days after she'd told friends was travelling to Woking and would then go on to a party.
But instead she went to Aldershot railway station and caught a train to London's Waterloo station, where she was caught on CCTV.
Her worried family issued an appeal for information, saying they feared she might be in danger.
