If there will be someone who would be courageous enough to stand and complain about the cheating happened then I bet the authorities who are also involved with the cheating/rigging will be forced to haul out someone to take the blame and will just bail them out if the issue will cool down because I don't think that the authorities and the brain behind it will reveal themselves in the spotlight just to get criticized.
But yes, cases like these usually happen locally where they have control of what will happen if things get worst. They wouldn't try to rig some big leagues as that could really end their career
But money talks louder than anything, especially with illegal things like this, authorities can haul it but only inside local leagues that obviously doing it but with big one, I doubt even there's rumor it still tough to prove since the facilitator are also good to work with every deal, they will not allow anyone to notice and have a solid evidence with the transactions that they are doing.
We can only say rumor, but proving it inside any big leagues will be tough, maybe next to impossible unless there's a really big name that will expose someone, but I doubt money will talk for sure.
