These guys set up a very slick looking sports arbitrage 'business' promising high returns, tax free with minimal to no risk. It was a scam from the start, basically working on the 'Ponzi' method. Take in a lot of investors cash, make a few big payouts, then close down and disappear.
Martin Dodge and Steve Nelson were some of the principals in this scheme and are being investigated by everyone from the ATO, police from a number of states and a few of their scammed investors. For more details on their nefarious activities visit:
