Beach guards at Naithon pulled two people, a man and a woman, out of the water. They were able to revive the woman, but had to perform CPR on the man.
Both victims were sent to Thalang Hospital for further treatment, but the man, Theechalat Kapang, later died in hospital.
The woman, Nattachanok Inamnoysri, 42, also a lawyer, but from Bangkok, told police they were on vacation. She said she and Mr Theechalat went into the water to wash off sand, but were dragged into the sea by a large wave.
“Where we washed our feet the seabed drops off suddenly. When the big wave hit us we slipped down the slope and the undertow pulled us further down into the sea,” Ms Nattachanok said.
