Friends are appealing for help finding 37-year-old Alice King, from Nunhead.
Alice left her home in Nunhead at 3pm on Friday, August 24, was seen at 4.30pm on Manwood Road, in Brockley, heading toward Catford and spotted by a friend at 7pm in Ladywell Road in Lewisham.
The mother of two is five-feet-four inches tall and weighs nine-and-a-half stone.
She was wearing jeans and a blue cardigan, and has brown hair, brown eyes and is white.
Alice has a distinctive fairy tattoo on her shoulder.
She is believed to not have a purse or phone on her, and her friends and family have not heard from her since Friday.
In a message for Alice on the missing people website, her family and friends said: “Alice we are here for you whenever you are ready.
“We can listen, talk you through what help you need, pass a message for you and help you to be safe.”
Anyone who thinks they have seen Alice, or who may know of her whereabouts, should call 101 or Missing People on 116000. Ref 18MIS034601.
