LONDON -- Forty-five more athletes, including 31 medalists, have been caught for doping after retesting of samples from the last two Summer Olympics, the IOC said Friday.The new cases bring to 98 the total number of athletes who have failed tests so far in the reanalysis of their stored samples from the 2008 Beijing Olympics and 2012 London Games.Using the very latest scientific analysis methods, the latest round of retests produced 30 provisional positive findings from Beijing and 15 confirmed positives from London, the International Olympic Committee reported.The IOC said 23 medalists from Beijing and eight medal winners from London were among those caught.No names were given.The IOCs news release cited 23 medalists from Beijing, but did not mention any from London. However, an IOC spokeswoman, Emmanuelle Moreau, confirmed later to The Associated Press that the London positive tests included eight medal winners.The IOC stores doping samples for 10 years so they can be retested when new methods become available, meaning drug cheats who escaped detection at the time can be caught years later.In a separate announcement Friday, the IOC stripped a Turkish weightlifter of her silver medal from the Beijing Games after her urine sample came back positive for steroids in new testing.The IOC said Sibel Ozkan tested positive for stanozolol and was ordered to return her medal in the 48-kilogram class. The 28-year-old lifter also faces a possible ban from the International Weightlifting Federation.Ozkan is the second athlete formally disqualified so far by the IOC in the retesting program. Last week, Ukrainian weightlifter Yulia Kalina was stripped of her bronze medal from the London Olympics after her sample came back positive for the steroid turinabol.The retesting program has targeted athletes who were in contention to compete at the upcoming Olympics in Rio de Janeiro, but has also been widened to cover many medalists.All athletes found to have infringed the anti-doping rules will be banned from competing at the Rio Games, the IOC said.The announcement comes at a time when the IOC is weighing whether to ban Russia from the Rio Olympics over allegations of systematic and state-run doping.On Thursday, the Court of Arbitration for Sport upheld an IAAF ban on Russias track and field athletes from the games. The IOC executive board is scheduled to hold a meeting Sunday amid calls by anti-doping bodies to exclude Russia entirely from Rio.The IOC said the previous first wave of retests had found 30 positive cases from Beijing and 23 from London. The Russian Olympic Committee has said 22 of those cases involved Russian athletes, including medalists.A total of 1,243 samples have been retested so far in the first two waves of the reanalysis program.The 30 new positive cases from Beijing involved athletes from four sports and eight countries.The 15 athletes caught in the new London tests represent two sports and nine countries.A third and fourth round of retesting will continue throughout and after the Rio Games, the IOC said.The new reanalysis once again shows the commitment of the IOC in the fight against doping, IOC President Thomas Bach said in a statement.The IOC said it was informing the national Olympic committees and international sports federations affected by the latest positives, clearing the way for disciplinary proceedings to begin against the athletes.The IOC said it could not provide more details, including the names of the athletes, for legal reasons.This will follow in due course, it said.The IOC reported in May that it had found 31 positives from Beijing. It said Friday that the backup B samples in two cases did not confirm the original finding, while an additional positive case was confirmed later. Andrew Toles Jersey .
