China has arrested the man who leaked top secret government documents from a North Korean prison camp detailing routine testing of chemical weapons on political prisoners, a report said. The man, who was not named, was seized by Chinese authorities after escaping across the border with his family, Radio Free Asia said, citing a South Korean human rights activist who recently appeared in a BBC documentary on the subject. “I made contact with this person in a chemical factory in North Korea a long time ago,” said the activist, Kim Sang-hun, who smuggled the documents out of the Stalinist nation. “He has been waiting, and waiting to obtain this document. Then he got the chance, and it was smuggled out of North Korea. His words were not enough. He wanted to show the evidence to the world, but he was captured in China.” Full Story
