BEIJING, Aug. 15 (UPI) -- The International Olympic Committee reported its first positive drug test involving a medal winner Friday at the Beijing Games
Kim Jong-su of North Korea, who won silver in the men's pistol competition and a bronze in the air pistol, tested positive for propanolol, a betablocker that limits trembling.
China's Tan Zongliang was moved up from third to second in the pistol and fourth-place finisher Vladimir Isakov of Russia will receive the bronze in that event.
In the air pistol, the bronze medal that had gone to Kim will now go to American Jason Turner.
The IOC said three athletes had tested positive among the 2,203 tests to date -- almost half of those tests having been conducted before the Games.
