She told officers her name was Mary Kofi, born on 27 April in either 1957 or 1947, but police say it is unlikely she was travelling under her real name.
Police said they were sure she was Ghanaian but that she had no identification papers or documentation with her when she died on 29 May.
The woman is described as about 40-years-old, 5ft 10in tall and of heavy build.
She had wavy black hair that appeared to have extensions, with slight tints of red.
UK Police have renewed appeals to identify a woman who died after apparently swallowing 61 packages cocaine. An image of the woman, who died shortly after arriving at Heathrow on a flight from Ghana, has been released in the hope someone will recognise her. She was found outside St Helier Hospital, Sutton, south-west London, after telling staff she was in pain.
