Powell, Simpson, Trainer Investigated in Italy Former 100-meter world-record holder Asafa Powell, Jamaican teammate Sherone Simpson and their trainer were formally placed under criminal investigation for violating Italy's doping laws, police said Tuesday. The move came a day after Italian police confiscated unidentified substances in a raid on the hotel where the three were staying in the northeastern town of Lignano Sabbiadoro, following the athletes' positive tests for banned stimulants. Udine prosecutors believe the three violated Article 9 of the doping laws, which calls for punishment for anyone who administers or consumes banned substances. Police were still analyzing the seized substances to determine whether they were legal. Being formally placed under investigation is a step up in the Italian justice system from someone simply "informed of the facts," which is how a person can be questioned by police. That occurred after the raid early Monday, when the three were brought to a local police station. Police told The Associated Press that the raids were executed after a tip from the World Anti-Doping Agency. Paul Doyle, the agent for the two sprinters, said they worked in conjunction with WADA on the raid after becoming suspicious that Christopher Xuereb, their newly hired trainer, might have given them supplements laced with a banned substance. Doyle also said that Powell and Simpson were aware of the impending raid, but Xuereb was kept out of the loop. "Asafa and Sherone have been tested more than 100 times each through their career ... and never turned in a positive test," Doyle told the AP in a phone interview. Now they change their supplements and the first time they get tested, they have a positive test? It has to be something in those new supplements that has caused it. Chris is the one that provided those. We're not trying to throw Chris under the bus and blame him for anything. We know it has to be something in the supplements he gave them. We're not saying he did anything deliberate, but it's in those supplements. We need to figure out what it was that caused this and from there move forward. An email to Xuereb wasn't returned. WADA director general David Howman likened this case to the doping scandal involving the Austrian cross country skiing and biathlon teams at the 2006 Turin Olympics, when Italian police raided athletes' residences after a tip from WADA and the IOC. "There's nothing new in relation to the way we operate," Howman added. Doyle said Tuesday the athletes had left Lignano but declined to say where they went. A hotel receptionist said late Monday that Xuereb had checked out. Powell and Simpson tested positive for the stimulant oxilofrine at the Jamaican championships last month, Doyle said Sunday, and the agent welcomed the investigation. That must mean they found something. That's good," Doyle said. The whole purpose of the raid was to see what products there were there and hopefully find whatever it was that caused this positive test. Asafa and Sherone were under the assumption and led to believe everything they were taking was completely legal. But Doyle acknowledged that he and the athletes should have been more responsible about what supplements they used.
