When approached for comment, the NSW Police media unit said in a statement: "For investigative reasons, no further information can be provided at this time."

The Australian Rugby League Commission has the power to suspend, fine or deregister players and officials who bring the game into disrepute. It's understood the issue has been referred to the NRL's integrity unit, although it's likely the governing body will wait for the police to present its findings.

In relation to criminal proceedings, the NRL's code of conduct states: "Where the breach of a provision of this code involving a player or a club official has occurred, and the conduct constituting that breach is the subject of a police investigation or criminal proceeding, the chief executive officer shall not proceed against that player or club official pursuant to part 2 of the NRL rules until the conclusion of that investigation or proceeding, as the case may be, unless the chief executive officer forms the view, in his absolute discretion, that it is appropriate to do so."

It's unclear how long it will take for the investigations to be completed, but as several current players and officials have gone on holidays it is expected there will not be a resolution for some time.

The development is the latest drama that has hit the Sea Eagles. Manly has this year performed well on the field, making their 10th consecutive finals appearance before being knocked out by the Bulldogs in a thriller.

As revealed by Fairfax Media last month, Anthony Watmough is poised to join Parramatta and could do so as soon as next season if he is granted a release from the final year of his contract.
