Police say the 15-year-old has been missing before but not for this amount of time and her family and officers are anxious for her to get in touch.

She is known to visit South Harrow and Harlesden, and officers say she was last seen wearing black tracksuit bottoms with paint on, a pink pyjama top and blue Nike trainers.

She is described as white, of slim build, approximately 5ft 2ins tall, with long light brown hair.
