Chief Superintendent Nigel Grimshaw said he could not "comment on disciplinarysanctions to individual officers" but said the PSNI has "learned many lessons from this investigation".
"Under IRB Regulations, and the application of the universality principle, all disciplinarysanctions handed down in rugby, including those arising from cross-border competitions, must be applied by all unions in membership of the IRB, " said a statement.
Over the last two years Fifa has also carried out 20 disciplinary investigations into the work of players' agents which led to sanctions in four of those cases.
