Alexandra Zurawaska is a young British girl who has not been seen since Christmas.
Fears are now mounting for the teenage girl who went missing on Christmas Day.
Authorities believe the 16-year-old may have travelled to Sutton, London, with an older man.
She also reportedly has links to Hounslow, Richmond, Brent and the Enfield boroughs of the capital.
Cops have described her as white, roughly 5ft tall and of medium build, with brown hair.
She was last seen in a khaki green coat with a fur-lined hood, a similar-coloured tracksuit and Timberland-style boots.
She also had a Land Rover bicycle in her possession.
A Met Police spokesman said: “Officers are growing concerned for her welfare.”
