(June 12, 2013) Beijing-based photojournalist Du Bin has been detained by Chinese state security officials after he disappeared following the release of his documentary on Chinese labour camp abuses — profiled here by Probe International last month. His sister, high-profile human rights activist Hu Jia, says Du is being held because his work directly challenges the authorities: “They are suppressing him to send a message to others,” she says.
