On the morning of 6 January 2021, Hong Kong police conducted a mass arrest of pro-democracy activists and former pan-democrat legislators for alleged subversion under the National Security Law. At least 53 people were arrested for their involvement in organizing the unauthorized “35+ Democrat Primary Election” held on 12 July 2020, to elect candidates for the now-suspended 2020 Legislative Council elections. The arrestees include a U.S. national who was allegedly involved in organizing the vote, which marks the first time a foreign national has been arrested under the law. If convicted under the National Security Law, the activists could face up to life imprisonment.
