A Serbian government official says arrested war crimes fugitive Radovan Karadzic used a false identity while on the run. Rasim Ljajic said at a Belgrade news conference Tuesday that Karadzic practiced «alternative medicine» and worked at a clinic while in hiding. Karadzic _ the Yugoslav war crimes tribunal's most-wanted fugitive _ was arrested near Belgrade on Monday night after a decade on the run, the Associated Press reported. Ljajic and Serbia's war crimes prosecutor Vladimir Vukcevic showed a photo of Karadzic with glasses, and with long, white hair and a beard. The prosecutor says a judge has ordered Karadzic's transfer to U.N. war crimes court in The Hague.
