A teenage girl missing for nearly two weeks may have travelled to Greenwich from her home in Gloustershire, police have said.
Hayley Kubiak, 19, has not been seen or heard of since October 11.
Police regard the teenager, from Stroud, as highly vulnerable and there is concern for her welfare.
She is described as white, 5ft 3, shoe size five, with shoulder length straight, dark-brown hair.
She has a medium build, brown eyes and a pale complexion.
It is not known what clothing she is wearing.
Police are asking anyone who sees Hayley or knows of her whereabouts to contact Gloucestershire Police on 101 urgently.
