Conrad Hooper was last seen by his family leaving home at around 1.30pm on Wednesday (18/9). The last sighting of Mr Hooper was at London Marylebone station later that day.
Police are concerned for his welfare, due to his physical frailty and mental state when leaving home. It is out of character for him to go missing for this length of time.
Mr Hooper is white, of stocky build and around 5ft 3ins. He is bald on the crown of his head with some grey hair to the back and sides. He was last seen wearing a cream jacket and light grey trousers.
He is thought to have links in Bournemouth, Brighton and Clapton, so may be headed to one of those areas.
