A paddle boarder was found by a fisherman after being killed by a shark.
The 53-year-old was discovered with evidence of shark bites near a beach in Noumea, New Caledonia in the South Pacific.
It is the latest in a string of shark attacks in the area since the beginning of the year.
The lifeless body of the boat driver was found last Saturday off the Nouville peninsula, which is on the main island of the French South Pacific.
An autopsy to confirm the cause of death is expected on Monday, reported Al Arabiya news.
“At this point in time, the investigators actually suspect a shark attack,” said public prosecutor Yves Dupas in a statement.
Authorities regularly issue shark warnings and warn swimmers to look out for a number of species in the waters around New Caledonia.
And there have been other shark attacks this year.
In February, a 57-year-old man was killed near Maitre Island after being bitten by a tiger shark that witnesses said was four meters long.
Authorities also suspect that the disappearance of a swimmer and a boat driver earlier this year could be due to sharks that have settled on the coasts near Noumea.
Meanwhile, 24 tiger and bull sharks were killed near the capital last month, which officials said were particularly large or aggressive.
Tiger sharks swim up to 60 miles a day, so they can be difficult to find.
French Polynesia banned shark fishing in 2006 and now the sea is full of creatures again.
