As they walked through arrivals at Manchester Airport, a couple seemed to be behaving oddly towards their baby. Something did not sit right with Border Force officers. One worried the relationship between the three was "not genuine". It was the start of a mystery that remains unsolved - the little girl's true identity is still not fully known.
Documents presented to the court said that she had been born to a young student in rural Nigeria, who was not able to care for her. Her father was not known. The papers indicated the mother had voluntarily relinquished Lucy to an orphanage. The couple had permission to foster the little girl but not to adopt her or take her out of Nigeria.
