Also Monday, Italian police confiscated unidentified substances in a raid on the hotel where Powell and Simpson were staying. Rooms of the athletes and physical trainer Christopher Xuereb of Canada were searched and drugs and supplements were seized, Udine police captain Antonio Pisapia told The Associated Press.
Pisapia said it was unclear if the substances were illegal, and that they were being analyzed.
“We are examining the substances now,” Pisapia said. “No arrests have been made and nobody has been placed under investigation.”
The raid took place at the Fra i Pini hotel in Lignano Sabbiadoro in northeastern Italy.
The doping positives come a month after another Jamaican Olympic champion, Veronica Campbell-Brown, tested positive for a banned diuretic.
In recent years, the IOC and International Association of Athletics Federations have focused on increased out-of-competition testing and storage of samples for retesting and retroactive sanctions. The IAAF and some other sports now use the blood passport system, which monitors an athlete’s biological profile over time for signs of cheating.
“While not perfect, the methods are ever improving, with blood passports and the ability to test athletes 24/7 in and out of competition proving to be effective in catching cheats and acting as deterrents,” Rogge said. “We also keep samples for eight years now so that improvements in testing can catch cheats long after the games are over.”
IOC vice president Thomas Bach, who leads the committee’s investigations into Olympic doping cases, said the latest news is “disappointing and encouraging at the same time.”
“Should all the information be confirmed at the end of the day it would be a great disappointment that some athletes obviously haven’t yet understood that there is zero tolerance in the fight against doping,”’ the German said. “Catching the cheats is important but only a means to the end of protecting the clean athletes.
