Middle-distance runner Bouchra Ghezielle has tested positive for the banned blood-booster erythropoietin (EPO), according to L'Equipe.

The French sports newspaper said traces of EPO were found following a random test in Franconville. No date was given for the test.

Ghezielle, who is Moroccan-born but now represents France, won the 1,500 metres bronze medal at the 2005 world athletics championships in Helsinki.

The 28-year-old also took part in this season's World Indoor Championships in Valenica, finishing seventh in the 1,500m.
