Fiji police say that state prosecutors won't hesitate to charge the former police commissioner, Colonel Isikia Savua, over the coup if they obtain enough evidence against him.
The police commissioner, Andrew Hughes, says Col Savua's file is still open and being actively investigated.
Col Savua, a former Prime Minister, Sitiveni Rabuka and a government senator, are among those cited in a police statement by Lieutenant Colonel Viliame Seruvakula as being involved.
Mr Hughes says the director of public prosecutions, Josaia Naiqulevu, will act if appropriate.
"I'm not predicting that we will be charging him, but that file, as I've said before publicly, is still open and we are actively investigating it. If there is sufficient evidence the DPP has shown that he has the stomach to proceed on these things, and proceed we will."
The police have come under increasing pressure to act following the leak of the damning police statement this week.
