LONDON (AP) — French runner Hassan Hirt tested positive for the blood-booster EPO, an official with knowledge of the result told The Associated Press on Friday. The IOC said he was ordered to leave the Olympics.

Hirt was tested during training in France on Aug. 3, according to the official. He said Hirt had been targeted by the French anti-doping agency for several months. The official spoke on condition of anonymity because he was not authorized to speak publicly about the case.
