Veronica Campbell-Brown is suspended after positive test for banned diuretic

Jamaica's twice Olympic 200 metres champion Veronica Campbell-Brown was suspended by her national federation following a positive test for a banned diuretic at a meeting last month.

"The Jamaican Athletics Administrative Association (JAAA) can now confirm that a case concerning Mrs Veronica Campbell-Brown is currently ongoing," the Jamaican governing body said in a statement. "She has been provisionally suspended from competition awaiting the outcome of a disciplinary panel that will be empanelled to hear this case."

The JAAA said the Caribbean island's most successful female athlete had voluntarily withdrawn from competition and accepted the provisional suspension. Campbell-Brown, 31, who was the first Jamaican athlete, male or female to win a global 100 metres title, tested positive for a diuretic, which can be used to mask the use of performance-enhancing drugs, at the International Invitational World Challenge on 4 May .

The JAAA had not previously identified Campbell-Brown but said it would empanel a disciplinary team to carry out a hearing as soon as it received notice of the B sample.

Sources close to Jamaican athletics told Reuters that the banned drug was contained in a cream which Campbell-Brown was using to treat a leg injury and which she had declared on her doping control form. They said an import-ant factor was if the banned drug appeared on the label of the cream.
