A leading French Polynesian union leader, Cyril Legayic, has been held in custody overnight and is to be presented to a judge to face possible corruption-related charges.
Public radio in Tahiti reports that police detained him for allegedly accepting money from employers to maintain the social peace.
This comes as Mr Legayic is due back in court in Papeete this week in the appeal court case over the so-called phantom jobs.
He was given a three-month suspended jail sentence for his role in accepting funds from the former president, Gaston Flosse, while also being on the union payroll.
Mr Legayic had claimed that he at all times maintained his independence.
He is among more than 40 others convicted for being on the public payroll to advance the political agenda of Mr Flosse's political party.
