The 15-year-old girl was reported missing when she failed to turn up for school and it emerged she had travelled to France with Forrest.
The pair were spotted on CCTV cameras on a cross-Channel ferry from Dover to Calais and later tracked to Bordeaux where they were recognised by a member of the public who had seen television coverage of the case.
He touted a bogus CV around bars in the city as he sought cash-in-hand work.
Before her disappearance, the schoolgirl told her mother that she was going to spend the night at a friend's house. Her mother said she was "really excitable" and was "jumping around". A message was later sent to one of her friends saying she had arrived safely in France.
The investigation was ramped up when she and Forrest failed to use return ferry tickets on September 23. A European Arrest Warrant was issued and the case featured on BBC's Crimewatch.
