One of three Greek sprinters found doping before the Beijing Olympics testified yesterday at a Greek inquiry into drug violations.

Dimitris Regas, a 400-metre runner, gave evidence to Athens prosecutor Costas Simitzoglou, judicial officials said.

Fifteen Gareek athletes, including Regas, tested positive for the steroid methyltrienolone this year, including eleven members of the Greek weightlifting team and one swimmer.

Regas tested positive during Olympic trials, while two other sprinters - Fani Halkia, the 2004 Olympic 400-metre hurdles gold medalist, and fellow sprinter Tassos Gousis - were expelled from the Greek Olympic team for allegedly using the same banned substance.

Judicial officials said Halkia and Gousis are both due to testify next week after prosecutors interview an International Olympic Committee official involved in the disciplinary decision against Halkia.
