ROME (AP) - 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 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 Christopher Xuereb, their newly hired trainer, might have given them supplements laced with a banned substance. Doyle also said 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 said.
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 he and the athletes should have been more responsible about what supplements they used.
"In hindsight, we should've been given a list, made sure we got a list," Doyle said. "The extent of what I did, I said to (Xuereb) in a text message, that all supplements have to be cleared by me first. He never cleared them with me. He did send them in an invoice that had the names of supplements in there that he had purchased. But that was it. I didn't have the ingredient list.
"Just looked at it this morning, 19 different supplements (Powell) was given."
Tara Playfair-Scott, Powell's publicist, said in a statement the runner handed over to police one bottle of Aleve containing 50 capsules and one bottle of 5-hour Energy, berry flavored.
Doyle added the athletes would ask for a backup "B" sample to be tested.
Jamaican athletes have made Lignano their in-season training base for years. A local track meet was scheduled for later Tuesday in Lignano, and Jamaicans had been scheduled to compete as they do most years. But neither Powell nor Simpson was on start lists released Monday.
The news of the positive tests for Powell and Simpson came the same day American 100-meter record holder Tyson Gay revealed he also tested positive.
Also Monday, discus thrower Allison Randall acknowledged she was one of the five Jamaican athletes who tested positive for a banned substance at the national championships last month, along with Powell and Simpson.
Randall holds the island's record for the discus throw and competed at the London Olympics.
The Jamaica Athletics Administrative Association issued a brief statement Monday saying an anti-doping management process has started for the athletes. It did not identify the two other athletes who tested positive.
Powell was the last man to hold the 100-meter world record before Usain Bolt broke it in 2008. He also helped the Jamaicans to the 400-meter relay gold medal at the 2008 Olympics.
Simpson won Olympic gold in the women's 400 relay in 2004 and silver in 2012, along with an individual silver in the 100 in 2008.
The findings come a month after another Jamaican Olympic champion, Veronica Campbell-Brown, tested positive for a banned diuretic.
