Efforts to trace missing woman Barbara Colling continued yesterday with specially-trained officers focusing their search on open land around Helmsley.
Officers carried out detailed searches from Newgate Bank along the B1257 back towards Helmsley and out to the Cleveland Way for Mrs Colling.
Police have said they are becoming increasingly concerned because she suffers from dementia.
Mrs Colling, 68, of Hemsley, was last seen walking along the B1257 near Abbotts Hag at around 9.30am on Monday.
Yesterday police urged members of the public to keep a look out for Mrs Colling and said it was possible she could have taken shelter in sheds, outbuildings or perhaps a church.
Insp Andy Everitt, said: “Barbara has been missing for a few days now and the public can really help with the effort to find her by reporting sightings of anyone matching her description.
“We know that Barbara likes churches and likes to visit them, so I would ask people who either work in churches or are regular visitors to be especially vigilant at this time.”
Mrs Colling’s daughter, Lizzy Firmin, earlier thanked the public saying: “The family has been overwhelmed by the lovely support we have had from neighbours and the whole community in Helmsley.
“Although mum does suffer from dementia people would probably not realise this unless they spoke with her, even then it may not be obvious as she may seem articulate and confident.”
Mrs Colling is described as 5ft 2in, with medium length blonde hair and was wearing a navy blue jacket and a blue hat with ear flaps. Call police on 101.
