His body is in the morgue at Vachira Phuket Hospital in Phuket City. The body will be buried in a pauper's unmarked grave on Phuket after 15 days if he is not identified in the meantime.
If you wish to see what the man looks like, go into the photo album above. There is nothing grisly or frightening about this man's photo in death - or we would not be publishing it.
We are simply concerned to prevent him being buried and forgotten if he has a loving family and friends who may not have yet noticed he is missing.
The man has a grey beard, spiky eyebrows, and a bent nose. He was wearing a gold earring, a gold finger ring and a crucifix on a gold chain around his neck.
He has some distinctive tattoos, and we have reproduced sandy photographs of those, too.
The man, aged 55 to 65, was pulled from the water at Nai Harn alive, but died before reaching hospital. Two Chinese caught in the same rip current that day were rescued.
The only other clue is the brown check trunks that he was wearing.
The man's death brought the total number of drownings on Phuket this monsoon season to six in the space of a month and a day, an alarming number.
Much more effort needs to be applied by officials, resorts and lifeguards to prevent further drownings.
If you recognise the man, please email firstname.lastname@example.org or call +66 76 255115.
