Police are growing increasingly concerned for the welfare of a vulnerable woman who has not been seen since October 24.

Patricia Dolton, who has links to the Croydon and Chelsea areas, was reported missing yesterday after not being seen for 17 days.

The 68-year-old needs regular medication that she is not believed to have access to.

She is white, about 5ft 9in with shoulder length frizzy blonde/ greying hair.

Ms Dolton, from Hammersmith, has access to a Freedom pass but does not have a mobile phone.

Anyone who sees her is asked not to approach her and call 999 immediately.

Anyone who knows of her whereabouts is asked to call police via 101.
