Police are on the hunt for the "good Samaritan" who helped rescue a teenage girl who was allegedly held captive and raped in Sydney last month.
The police statement said that on the morning of April 27, the girl escaped from the house and ran until she was picked up by an unknown woman, who drove her to the Newtown Asylum Seeker Centre centre.
The girl had met the man who kept her captive in Guinea in January, and the pair travelled back to Australia via Paris in early April.
She was allegedly taken to a house and sexually assaulted by "a number of men" until her escape on 27 April.
The girl was then taken to Royal Prince Alfred Hospital before being placed into the care of Family and Community Services.
The New South Wales State Crime Command are appealing for the woman who picked her up, believed to be named Nicole, to come forward.
NSW Police and Australian Federal Police have appealed for that woman, who was driving a small red auto, believed to be a hatchback, to come forward to help with the investigation.
The girl, named in USA court documents was "Jane Doe", was reported missing on April 11 and a search of flight records revealed she had left the country, Australian Federal Police told AAP.
Specialist detectives from the NSW Police Sex Crimes Squad have also formed Strike Force Stockall to investigate the circumstances surrounding her ordeal.
Police are also keen to speak with anyone who may have seen or heard the girl after she escaped from the home.
