Frank Bainimarama's illegal regime is carrying out a major military probe into attempts to overthrow him.
A fourth man was taken in for questioning last night - Felix Anthony, the General Secretary of the Fiji Trade Union Congress - and it's believed two high ranking officers have also been questioned.
The officers have been named to Coupfourpointfive as the deposed land force commander, Pita Driti, and Brigadier General, Mohammed Aziz.
We are seeking more information about this development, especially the inclusion of Aziz in the sweep, but military sources have told us the regime is currently conducting a major army operation to identify dissenters and plotters.
We've been told the three men who were questioned earlier this week - former cabinet ministers Poseci Bune and Anand Singh, plus businessman Ben Padarath - were interrogated about 'suspicious' documents.
Coupfourpointfive has been told documents, apparently of a plan, were found in Padarath's Suva home.
Readers will recall that late last year, tension and soured relations boiled over at camp and it was widely believed disenchanted officers were to remove Bainimarama.
Footnote: Felix Anthony was released after five hours in custody. Padarath is in hospital for burns received during his interrogation. See earlier Coupfourpointfive stories.
