Police are increasingly concerned to know the whereabouts of Edwin Salmon, 81, who is missing from Tottenham since midday on Tuesday, 26 November.
Edwin suffers with dementia and may appear confused. He wandered off while shopping in Wood Green with his wife and she is desperate for news that he is safe.
He is described as a black man, 5ft 8ins tall, of slim build with short grey hair. When last seen he was wearing a light blue jacket, grey trousers and a light brown hat.
He was pushing a blue shopping basket.
Edwin does not have a freedom pass, Oyster, mobile phone or credit card so will be unable to contact his wife without assistance.
He frequents the allotments at White Hart Lane and Holloway Seventhday Adventist Church, Holloway Road, N7.
Anyone who has seen Edwin should call police on 101 quoting 19MIS046973 or call Missing People on 116 000.
