IAAF chief confirms positive drugs test
IAAF president Lamine Diack confirms failed drugs test by top athlete
IAAF president Lamine Diack has been informed of a positive drugs test by a leading athlete.
A report in French sports daily L'Equipe has named Morocco's Mariem Alaoui Selsouli, the favourite for the Olympics 1,500m gold medal, as having tested positive for a banned diuretic. Diack said he had been informed about the positive test.
He told the Press Association: "I have heard about it last night. I will not make a comment other than you will follow the rules or you will be suspended."
The Moroccan national Olympic committee said they are expecting the IAAF to communicate on the issue.
Selsouli served a two-year doping ban from 2009 to 2011 for an earlier doping offence and would have missed London had the International Olympic Committee not lost a court case banning drugs cheats from the next Games even if their suspension had expired.
She set the best time in the world this year of 3min 56.15sec in Paris last month after which she was tested.
