The teenage Guinean national walked into the Asylum Seeker Centre in Sydney’s inner west on April 27, a joint statement from the Australian Federal Police and NSW police force said.
She told staff she had been dropped off by a woman who found her after she had escaped from a house, where she had been held captive and regularly sexually assaulted.
Investigators from the federal and state police force have been told the girl met a man in her home country, Guinea, in January, who offered to bring her to Australia to work as his cleaner, police said.
In early April, the girl travelled with him from Guinea to Sydney, flying via Paris.
After arriving in Sydney, the man drove her to house at an unknown location – “believed to be in the Sydney Metropolitan area” – where she was kept in a room and sexually assaulted by a number of men, police said.
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 was taken to the University of Technology’s anti-slavery unit before going to the Royal Prince Alfred hospital for treatment.
Police have appealed to the public for information to identify the “Good Samaritan” who assisted the girl who was “in fear for her life”.
It is believed the woman’s name is Nicole and she drives a small red car, possibly a hatchback.
The AFP’s Human Trafficking Unit is continuing their inquiries to determine when the girl arrived in Australia, and identify the man with which she travelled.
