Weightlifting's governing body today banned Kazakhstan's double Olympic champion Ilya Ilyin and three other gold medalists for failing dope tests at the 2012 London Olympics. In all, ten lifters were banned after dozens of London samples were retested. Kazakhstan's biggest Olympic hero, Ilyin took 94kg gold in Beijing and London and was to go for a third straight title in Rio de Janeiro in August. He tested positive for anabolic steroids. Three other Kazakh gold medalists from London — Zulfiya Chinshanlo (53 kg), Maiya Maneza (63 kg) and Svetlana Podobedova (73 kg) — also failed tests and were banned, theIWF said. Others include Azerbaijan's 58kg world champion Boyanka Kostova and Russia's London 85kg silver medal winner Apti Aukhadov. The IOC is retesting samples to catch cheats who might be competing at the Rio de Janeiro Olympics in August.
