The family of the French Polynesian journalist who disappeared in 1997 has responded to comments made by the veteran politician Gaston Flosse.
Mr Flosse accused the journalist's brother of orchestrating a rumour campaign to implicate him into an alleged plot.
The family says they want to find out the truth behind the sudden disappearance of Jean-Pascal Couraud.
The case won fresh attention last month when the family's lawyer revealed that a letter was found in Mr Flosse's possession, giving an account of how Mr Couraud was seized and drowned by four men working for the now disbanded GIP intervention force.
Mr Flosse says the document, purportedly written by one of the alleged abductors who died five years ago, is a fake.
Last week, he announced that he had taken legal action against several media over the affair but the nature of the complaint is not known.
