A high risk person has gone missing and concerns about her welfare are increasing.

Janet Copping, a 76-year-old with severe Alzheimer's and anxiety, left her house in Finchley at 12.10pm today and has not been seen since.

In June Ms Copping went missing for three days and was found very weak in Southgate at 3am, and officers did not believe she had eaten or drunk since leaving her home and she could not recall where she had been.

Ms Copping left today wearing black trousers and a black jacket with a black shoulder bag containing £20, and she has no phone, Oyster card or her tracker device.

If you see her or know of her whereabouts please contact Barnet Police on 020 8733 5870 or 020 8733 4040.
