He doesn't know why, but he wants to be called Frank.
A week after he apparently awoke on a beach in Kent, southeast England, with no idea who he is or how he got there, however, his identity is bewildering police and the local community.
The polite and well-spoken man, thought to be in his early 50s to late 60s, turned up at Victoria Hospital in the coastal town of Deal last Thursday clutching sunglasses, a walking stick and a packet of cigarettes.
Dressed tidily in a white T-shirt, black jeans and a patterned sweatshirt, and prepared for the elements with a navy blue walker's coat and beige walking boots, he is believed to have been living relatively normally until all knowledge of his past life deserted him.
Police have issued a photograph and called for the public's help. Detective Sergeant Shaun Creed said the man seemed "quite calm, a little bit withdrawn but not overtly distressed".
