Zainab al-Hilli, the seven-year-old who survived the French Alps shooting, in which her mother, father and grandmother were killed, has left France for the UK.
The schoolgirl was placed in a medically induced coma after she was shot in the shoulder and badly beaten in the massacre which killed her father, mother and grandmother.
The child, who is seen as one of the key witnesses in the case, left hospital at about 8am on Friday, accompanied by British police.
Zainab's medical condition has dramatically improved in recent days, allowing her to travel back to the UK.
A police source in Annecy told the Press Association: "Zainab left France this morning at around 8am.
The ali-Hilli's home in Claygate, Surrey, has been searched by police
"Police from Britain accompanied the little girl."
Zainab will join her younger sister, Zeena, who returned to the UK earlier in the week having escaped the brutal attack unscathed.
The four-year-old survived by hiding beneath her killed mother's skirts and was discovered eight hours after the killings.
The bodies of Saad al-Hilli, 50, his dentist wife Iqbal, 47, and her elderly mother were discovered in their family's BMW in a remote car park near Lake Annecy at around 4pm last Wednesday.
Next to the vehicle lay the body of Sylvain Mollier, 45, a French cyclist who apparently stumbled across the attack.
Another cyclist - the first to arrive at the scene - has described how he spotted Zainab "stumbling" around, bleeding and "moaning" near the car.
Brett Martin, 53, likened the carnage to a set from TV crime series CSI: Miami.
Martin, who has been credited with saving Zainab's life, turned his attention to the little girl, first moving her body from where it lay in front of the car, fearing the vehicle could lurch forward and crush the child.
He placed her in the recovery position and a few minutes later, she fell unconscious.
She appeared "severely injured" and there was "a lot of blood", he said.
