Sprinter Kelly Ann-Baptiste of Trinidad and Tobago reportedly becomes the latest athlete to fail a drug test a day before the start of the 100m heat, a category in which she won gold in Daegu two years ago, at the 2013 IAAF World Championships.
Baptiste, the third fastest woman in the 100m this year, was also due to campaign in the 200m and the 4×100m relay but has since been sent home.
She joins Veronica Campbell, Asafa Powell and training partner Tyson Gay among high profile sprinters to have tested positive in the past few months.
“(Ann-Baptiste) voluntarily withdrawn from the meet and has left the team’s village and is back at her base,” manager of Trinidad and Tobago team, Dexter Voisin, said.
The 10.83secs the 26-year-old sprinter ran in a national championship at Port of Spain, Trinidad in June leaves her third behind Shelly-Ann Fraser-Pryce and Blessing Okagbare in this year ranking.
She finished third over 100m in last month’s London 2012 Anniversary Games.
