This isn't good news: an investigation has resulted in a confession from a German referee that he fixed professional games. This has been a growing and disturbing trend in Europe. I suppose it's good that it's being uncovered, but you have to wonder how deep the problem is, and how long it's been going on.
This article says the ref in question was involved with Croatian gambling rings. Where else do their tentacles reach? Remember the first rule of investigations: Follow the money.
I think this is going to be a very big story.
