Police are continuing to search for Lynda Foulkes, who went missing from her home in Greater Manchester on July 10.
Superintendent Alan Veitch said:
"Lynda grew up in the Gosforth area of Newcastle and although she has since moved away, she still has family living in Newcastle and has strong links to this area.
"She used to visit Wallington Hall when she was a child and we believe she may be in that area now. "We also know that she has links to the Whitley Bay area, in particular St Mary's Lighthouse and used to enjoy sitting on the benches overlooking the sea.
– Superintendent Alan Veitch, Northumbria Police
"She loves the outdoors, in particular rural areas and the coast, so we are asking people who are out and about in our area to keep an eye out for Lynda and contact us if they see her, or think they may have seen her.
"She has not been seen since Thursday afternoon and we are become increasingly concerned for her welfare, so we are asking people to contact us immediately if they have any information that would help to locate her.
"We are also appealing for Lynda herself to contact us and let us know she is okay."
