A tour guide from Manta Marine Co called the Similan Marine Rescue Unit for assistance at 12:45pm yesterday when one of the tourists in his group fell unconscious whilst snorkelling.
The rescue unit immediately went to assist, and due to the severity of the man’s condition decided to transport him via speedboat to the Navy Base Hospital in Thai Muang in Phang-nga where he was later pronounced dead.
Police are in the process of contacting the Chinese embassy and informing the victim's family.
