Kenyans informed of Lagat's positive test

Kenyan track authorities discovered Olympic medalist Bernard Lagat tested positive for a banned substance four days after the start of the World Championships.

Lagat tested positive for erythropoietin, or EPO, a drug that enhances stamina by increasing oxygen-carrying red blood cells. He was in Paris for the 1500 meters, but did not compete. His absence from the event was attributed to illness.
