An elite runner from Sierra Leone who disappeared after finishing the women's race at the London Marathon in 20th place remains missing.
Scotland Yard launched an appeal to find 24-year-old Mami Konneh Lahun, when she did not return to her temporary accommodation in Greenwich, where she had been staying since arriving in the UK on April 7.
Police said earlier that she had been found in Greenwich, but later reissued an appeal.
They said she was due to fly home yesterday. The runner has no known links to the UK and was not in possession of a mobile phone.
