Fiji police are trying to ascertain how a statement made to them over an alleged plot to kill all government MPs was published by a British-based website.
Parts of the statement made by an internet cafe owner, Rajneel Singh, in late December were in the past week reproduced by the website Fijileaks.
In November, Mr Singh said he found details of the plot on an unattended computer in his cafe and called police, who he claims then assaulted him.
Mr Singh was briefly treated in hospital while under military guard.
No assailant has been identified.
Fiji police said they were in touch with the internet company Google in the US to try to track down those behind the alleged plot.
The acting police commissioner, Brigadier General Sitiveni Qiliho, earlier told the Fiji Times that overseas counterparts had also been contacted, but the newspaper report gave no further details.
Mr Singh said he was warned in e-mails against assisting in police investigations, that his house was broken into and his family's life was threatened.
