The Karadzic arrest is now a "top-story" on google. There are a number of articles on the arrest of Karadzic and various reactions; (now summarized in this handy guide) but not surprisingly, they are short on details of the actual arrest. Although I expect that to change over the next few days.
Rhetorical question: I wonder how long until the obligatory "free Radovan" website pops up?
No doubt it will contain the good doctor's poetry.
