Austria, long seen as a doping paradise in Europe, has made a series of major arrests, including that of alleged big fish Stefan Matschiner, the former manager of cyclist Bernhard Kohl, who was suspended last year for doping.
Matschiner was arrested overnight by the new anti-doping task force, just hours after returning from the United States.
He was present at the 2006 Winter Olympics in Turin when the Austrian biathlon and cross-country squads were found in possession of banned substances and equipment.
And Matschiner was she manager of Danish cyclist Michael Rasmussen when he was excluded from the 2007 Tour de France for missing doping tests.
Unntil now he had never been considered a suspect but that changed after the triathlete Lisa Huetthaler, 25, named him as one of her main suppliers of banned blood booster EPO.
