His family has not seen or heard from him since, with relatives said to be ‘growing increasingly concerned for his welfare’.
David is white, tanned, around 6ft tall, of a medium build and has short, brown hair.
He has tattoos on his forearms and shoulders and it is believed he may be carrying a large blue duffle bag and a walking stick.
