Nuon Chea, the oldest living member of the Khmer Rouge regime was arrested this week by Cambodian police.
Nuon Chea, better known as Brother No 2, was seized from his house near the Thai border and charged with crimes against humanity. The second-in-command to the Khmer Rouge leader Pol Pot, his arrest is the boldest move yet made by the UN-Cambodian tribunal, which was set up last year to investigate one of the bloodiest periods of rule in modern world history.
The Cambodian tribunal has been plagued by legal sidestepping and a bureaucratic malaise that finally began to end earlier this year as the court decided on key principles and paved the way for enlisted the judges necessary to begin the proceedings.
