Police are appealing to trace a vulnerable teenage girl who is believed to be in London.

Alexandra Zurawaska, 16, was last seen at around 19:00hrs on Monday, 25 December in South Yorkshire.

Since then, she is thought to have travelled to Sutton. Alexandra also has links to Hounslow, Richmond, Brent and Enfield boroughs.

She is a white female, around 5ft tall and of medium build, with brown hair.

When last seen, Alexandra was wearing a khaki knee-length coat with a fur-lined hood, khaki tracksuit trousers and Timberland-style boots.

She was also in possession of a Land Rover bicycle.

She may be in the company of an older man.

Officers are growing concerned for her welfare. Anyone who has seen Alexandra is asked to call police 101 or tweet @MetCC.
