COPENHAGEN, Denmark (AP) -- A report by Denmark's anti-doping agency says Bjarne Riis chose to ignore drug-taking by riders on the former Team CSC.
Michael Ask, head of Anti-Doping Denmark, says Riis "failed to intervene," and "it is totally unacceptable."
The 97-page report published on Tuesday was based on 50 interviews with present and former riders, aides, and officials, including disgraced Danish rider Michael Rasmussen.
Rasmussen was leading the 2007 Tour de France when he was sacked by his team for lying about his whereabouts when he missed pre-race doping tests. In 2013, he admitted he doped for more than a decade.
Riis revealed in 2007 that he used blood-boosting EPO to win the Tour in 1996. He later managed CSC, which eventually became Team Saxo-Tinkoff.
