North Yorkshire Police have issued a statement about the search for Annie (which I have edited below for brevity):
Officers from North Yorkshire Police are extending their appeal to locate a missing person to Sidcup in South East London.
Annie Dryden, 20, was initially reported missing to Cleveland Police with enquiries leading North Yorkshire Police obtaining primacy of the investigation on Wednesday, 10 January.
Today (Wednesday, 24 January) officers have asked the Metropolitan Police Service to share their appeal with local media and their communities after links between Annie and Sidcup were established.
Senior Investigating Officer Detective Chief Inspector Fionna McEwan, said: “The focus of our search is still very much in the North Yorkshire and Cleveland areas where the last confirmed sightings of Annie were. We do not want people in these areas to stop looking out for Annie or not report any potential sightings of her.
“However, as Annie has not yet been located in these areas and we know she has links to south east London we wanted to extend our appeal to those in this area.
“Although the appeal to find Annie has been prominent in the North East of England and Yorkshire, if Annie has travelled south she may not be fully aware of the coverage, which is why we are now asking for our appeal to be shared in this area.
“We needed to do this to help find you. Once we know you are ok, we will remove your image from our website and social media channels and will work with the media to do the same."
