ROME -- Police say former 100-meter world-record holder Asafa Powell, Jamaican teammate Sherone Simpson and their trainer are under investigation for violating Italy's doping laws.
The move comes 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.
The trainer is Christopher Xuereb of Canada.
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 are still analyzing the substances confiscated.
Jamaican athletes have made Lignano their in-season training base for years.
