Athletics: Campbell-Brown linked with failed test
Jamaica's 200m world champion Veronica Campbell-Brown has tested positive for a banned diuretic, according to sources.
The sources said the doping violation occurred at the Jamaica International Invitational meeting on May 4 in Kingston.
Jamaica Athletics Administration Association (JAAA) president Warren Blake said an athlete had tested positive at the meeting but didn't give a name.
"What I can confirm is that we do have an adverse analytical finding coming out of the May Invitational meet," he said.
"We've not as an association been informed of the result of the B sample testing. As such I'm not able to speak the name of the athlete or to say anything that may identify which athlete it is," he added.
Campbell-Brown is Jamaica's most successful female athlete and the biggest name in track and field to fall foul of the testers since American sprinter Marion Jones.
Jones served a six-month prison sentence and was stripped of the five medals, including three golds, she won at the 2000 Sydney Olympics after admitting to using performance-enhancing drugs.
Local media reports said Campbell-Brown had been present at the laboratory in Canada when her B sample was tested.
The finding comes after Jamaican 400m runner Dominique Blake received a six-year ban on Thursday for her second doping violation since 2006.
