World athletics body suspends Moroccan 1,500 runner Selsouli from London Olympics for doping

LONDON - The IAAF provisionally suspended Moroccan 1,500 metres runner Mariem Alaoui Selsouli from the London Olympics on Wednesday after she tested positive for doping.

The governing body said Selsouli tested positive for the diuretic furosemide at the Paris Diamond League meeting on July 6.

Selsouli became an Olympic medal favourite after timing 3 minutes, 56.15 seconds in Paris — more than four seconds below her previous personal best.

"Selsouli has waived her right to the B (backup sample) analysis, and as a result has now been provisionally suspended from all competition in athletics," the IAAF said in a statement.

The IAAF said can still request a hearing by the Moroccan Athletic Federation that needs to be held within the next 3 months. The governing body said it will not make any further comment on the case in the meantime.

If found guilty, the 28-year-old runner faces a lifetime ban for a second doping offence of her career.

Selsouli finished serving a two-year ban last August for using EPO before the 2009 world championships.

Furosemide is included on the World Anti-Doping Agency list of prohibited substances. It can also be used as a masking agent to disguise the presence of other performance-enhancing drugs.
