POLICE are concerned about the welfare of a woman who has been missing for almost a month.

Theresa Cook, of Carlisle, was seen in Durham on November 17 but has not been seen since.

The 39-year-old is described as a slim, white female, 5ft 4ins, with shoulder-length hair.

Officers believe she could be in Durham, but could also have travelled back to Carlisle.

They would like anyone with information about her whereabouts to get in touch with Cumbria Police via 101.
