Several people have been questioned and released as investigations into the registration of ships in Fiji through the use of falsified documents are progressing.
The investigation is being done by the Maritime Safety Authority of Fiji and Police.
Police have confirmed that they are only investigating the process involved in the registration of a foreign ship in Fiji.
Police are also trying to establish if this is linked to a much bigger operation.
The Maritime Safety Authority of Fiji has submitted all the information to the Fiji Police Force and also filed a police report in the process.
It has also confirmed that other countries in the region have been notified about the investigation.
CEO John Tunidau had said Fiji does not have an open registry and as such foreign ships claiming Fiji is their Flag state are doing so fraudulently.
An open registry is a practice where foreign ship owners register their ship in another state.
A spokesperson for the Maritime Safety Authority of Fiji says they cannot comment further on this matter until investigations are complete.
