Jamaica's two-time Olympic 200 metres champion Veronica Campbell-Brown has been suspended by her national federation following a positive test for a banned diuretic at a meeting last month.
Jamaican officials say the Caribbean island's most successful female athlete had voluntarily withdrawn from competition and accepted the provisional suspension.
The 31-year-old Campbell-Brown, 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 in Kingston in early May.
The 200 metres world champion has yet to comment.
