Police officers are “extremely” worried about a vulnerable 13-year-old girl from St John’s Wood who has been missing for four days. Kayley Lynch was last seen in the Harrow Road area of Westminster at about 5.30pm on Friday.

She was supposed to return to her St John’s Wood home by 11pm. Kayley is described as white, about 5ft 6in tall, of a medium-large build and has brown hair with blonde highlights. She was last seen wearing light-coloured jeans, a black top, a short black jacket and black shoes.

Officers, who said they are “extremely concerned for her safety and wellbeing”, believe she could be anywhere in the capital.
