Moroccan 1500m runner Mariem Alaoui Selsouli has been thrown out of the Olympics after testing positive for a banned substance.
The 28-year-old was found to have the banned diuretic furosemide in her system following a meet in Paris on July 6, when she smashed her personal best by four and a half seconds.
Selsouli, who now faces a lifetime ban, declined the option of having her B sample analysed, but still has the right to a hearing.
The International Association of Athletics Federations have released a statement this morning, which read: "IAAF is now in a position to officially confirm that the prohibited substance furosemide (a diuretic) was found in Mrs Alaoui Selsouli's sample collected at the Meeting Areva in Paris on 6 July, 2012.
"Alaoui Selsouli has waived her right to the B analysis, and as a result has now been provisionally suspended from all competition in athletics. In accordance with IAAF rules, she still has the right to request a hearing which needs to be held by the Moroccan Athletic Federation within the next three months.
"Until such time, the IAAF will make no further comment on this case."
Selsouli served a two-year ban from 2009 for a previous failed test.
