Julie Ella, 51, who police believe may be in central London or Cambridgeshire, was last seen at her home on August 14. Since then she has been seen at St Neots railway station on August 23, and it is believed she intended to go to London, but this has not been confirmed. Julie, who is white, 55, with dark brown wavy shoulder length hair, was last seen wearing a grey billabong coat, grey leggings and white Nike trainers with pink detail, and was carrying a large grey rucksack and a Bag For Life. A spokesman for Cambridgeshire police said: There is increasing concern for Julie as she is vulnerable and although there are no suspicious circumstances around her disappearance it is important that she should be found as soon as possible.
