Four key members of the group behind Hong Kong's annual Tiananmen Massacre vigil [7] were arrested Sept. 8. The arrests came the morning after the activists publicly refused a police demand for information [9] as part of a "national security" probe into the 32-year-old group. The Hong Kong Alliance in Support of Patriotic Democratic Movements of China [6] said its vice-chair Chow Hang-tung and committee members Simon Leung, Tang Ngok-kwan and Chan To-wai were arrested in the early-morning raid on the June 4 Memorial Museum [8]. Police confirmed the arrests, saying the four, aged between 36 and 57, are being held for failing to comply with Article 43 [10] of the National Security Law [11], which compels cooperation with investigations. The police had requested information from the group in a letter late August [12] under provisions of Article 43. The force also alleged that the group had been working with foreign agents, a potential violation of the Beijing-imposed legislation. (HKFP [15], The Guardian [16])
