Among the allegations relating to the salary cap rorts at the Eels, were claims of falsified invoices for services or goods that were never delivered.
Such allegations are expected to be among those investigated by police.
Earlier on Thursday, the five Parramatta officials at the centre of the salary cap scandal submitted their responses to NRL show-cause notices seeking their deregistration.
The fate of Eels chairman Steve Sharp, chief executive John Boulous, directors Tom Issa and Peter Serrao and football manager Daniel Anderson sits in the hands of the NRL integrity unit and CEO Todd Greenberg after lodging their individual responses to the governing body's claims.
The Parramatta club has until Friday to provide its separate submission over the alleged salary cap breaches.
A final determination is expected from the NRL within a fortnight.
On Tuesday the NSW Supreme Court upheld the NRL's provisional suspension of the so-called "Gang of Five" club officials.
The five had been asked to show why they shouldn't be deregistered for their part in the club's alleged systemic salary cap breaches.
The club has been threatened with the loss of 12 competition points, their 2016 Auckland Nines title and a fine of $1 million.
