The World Anti-Doping agency says the criminal underworld now controls much of world sport.
WADA's director-general, New Zealander David Howman, has told a doping conference convened by the World Sports Law Report at Twickenham rugby stadium that the criminal elements who control illegal betting are also involved in steroid trafficking.
Howman says there's more money made in trafficking illegal performance-enhancing drugs than in dealing heroin, and he says his information comes from law enforcement agencies including Interpol, who are seriously concerned about the scale of underworld operations.
