A Jamaican athlete has reportedly returned an adverse analytical finding, from tests carried out on her 'A' sample at the May 4 Jamaica Invitational staged inside the National Stadium.

The identity of the athlete, said to be of international repute, has not been confirmed.

Several officials of the Jamaica Anti-Doping Commission expressed surprise at the reports, informing that the random tests carried out of the meet was not conducted by the commission, but rather, by an international team facilitated by the IAAF.

Jamaica Athletics Administrative Association president, Dr Warren Blake, when contacted yesterday, also claimed to be in the dark, noting that he had been in surgery all day and will be making an effort to gather as much information as possible today.

The athlete has been notified by the authorities and has seven days in which to request that her 'B' sample be tested as well.

The identity of the athlete, said to be of international repute, has not been confirmed.
