KINGSTON, Jamaica _ An unidentified Jamaican athlete who was part of a team that won two medals at a recent international meet tested positive for a banned substance, according to a Jamaican newspaper report.

The athlete has requested the B sample be tested, the Jamaica Observer reported, citing unnamed sources.

The athlete was part of a team that won gold in the women’s 60 meters and bronze in the women’s 4×400 relay at the March meet in Qatar.

Howard Aris, president of Jamaica’s track and field federation, told The Associated Press on Friday that he had no information.

“I haven’t heard anything about any failed drugs test,” he said.

Last year, four Jamaican runners admitted to using a banned stimulant before Jamaica’s National Championships.

Yohan Blake, Lansford Spence, Marvin Anderson and Allodin Fothergill were suspended for three months.
