2004 Ukrainian child pornography raids
The 2004 Ukrainian child pornography raids occurred a few months before the First Orange Revolution, when police in Ukraine raided a softcore child pornography ring operating in the cities of Kyiv, Kharkiv, and Simferopol. The ring had operated since 2001 and used a modeling agency as a front.
