The head of Europol, Rob Wainwright, said an investigation into match-fixing has uncovered a "big problem" for football's integrity:
This is the work of a suspected organised crime syndicate based in Asia and operated with criminal networks around Europe.
It is clear to us this is the biggest-ever investigation into suspected match-fixing in Europe.
It has yielded major results which we think have uncovered a big problem for the integrity of football in Europe.
