After Jamaican sprinters Asafa Powell and Sherone Simpson tested positive for banned stimulants, Italian police raided their hotel and confiscated unknown substances in a raid Monday, The Associated Press reported.
Rooms of the athletes and trainer Christopher Xuereb of Canada were searched and drugs and muscle supplements were seized, Udine police captain Antonio Pisapia told the Associated Press.
Pisapia said it was unclear if the drugs and muscle supplements were legal or illicit and that the substances were being analysed.

"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 northeast Italy.
Powell, a former 100m world record holder, and Simpson tested positive for the stimulant oxilofrine at the Jamaican championships last month, their agent announced on Sunday.
The police captain with the specialised NAS unit added that Powell and Simpson were informed of the positive tests on Saturday morning.
A local athletics meet is scheduled for Tuesday in Lignano and the Jamaicans had been scheduled to compete as they do most years. However, neither Powell nor Simpson were on start lists released on Monday.
The news of the positive tests for Powell and Simpson came the same day that American former 100m record holder Tyson Gay revealed he had also failed a doping test.
Powell was the last man to hold the 100m world record before Usain Bolt broke it in 2008. He also helped the Jamaicans to the 4x100m relay gold medal at the 2008 Beijing Olympics.
Simpson won Olympic gold in the women's 4x100m relay in 2004 and silver in 2012, along with an individual silver in the 100m in 2008.
The doping positives come a month after another Jamaican Olympic champion, Veronica Campbell-Brown, tested positive for a banned diuretic.
In another development, Adidas on Monday suspended its sponsorship of Gay after the American's positive doping test.
