Tahri was implicated by La Monde earlier this year... ghost, I think you live in a naive cave.
From Le Monde, dated 26.07.07 and translated by Google:
"E French medium-distance race did not finish the spring cleaning begun at the summer 2006. According to our information, in a dated June 27 mail, the Moroccan half-founder Aïssa Dghoughi forwarded to the medical commission of the international Federation of athletics (IAAF) a list of French athletes to which it is shown to have provided doping products. In this letter, it also affirms that its compatriot Khalid Skah, Olympic champion of the 10.000 m in 1992 and champion of the world of cross-country race in 1990 and 1991, and a manager German athletes, Dorothee Paulmann, would have done as much of it.
Among the athletes blamed appear the ex-recordwoman of France of the 1.500 m Latifa Essarokh, and the ex-champion of France of cross-country races Khalid Zoubaa, which currently purge respective suspensions of two and three years for positive controls with the stanozolol (steroid anabolic) for the first and with the EPO for the second.
But Aïssa Dghoughi also quotes Yamina Bouchaouante, Julie Coulaud, recordwoman of France of the 3.000 m steeple, Bouchra Ghezielle, bronze medal-holder on 1.500 m with the championships of the world of 2005, Mustapha Tantan and Bouabdellah Tahri, former Co-recordman of Europe of the 3.000 m steeple.
Khalid Skah, according to him, provided products to Essarokh, Zoubaa and Bouchaouante. As for Dorothee Paulmann, which lives in Trier (Germany), former wife of a doctor, ex-triathlète and to manage approved by the IAAF of the Kenyan half-caster Edith Masai, it would provide “regularly” Bouabdellah Tahri in prohibited products."
There's more. If there's one thing we've learned over the last few years is that most of these allegations eventually prove themselves true.
