HONG KONG — Hong Kong authorities arrested a Roman Catholic cardinal, a singer, and at least two others on Wednesday on suspicion of colluding with foreign forces to endanger China’s national security, reports said.Cardinal Joseph Zen, singer-actress Denise Ho, lawyer Margaret Ng, and scholar Hui Po-keung were detained by Hong Kong’s National Security Police, a U.K.-based human rights group, Hong Kong Watch, said.The arrests were apparently related to their roles as trustees of the 612 Humanitarian Relief Fund, which provided legal aid to people who took part in 2019 pro-democracy protests that were quashed by security forces, the group said. The fund closed in 2021, it said.Scores of pro-democracy activists have been arrested under a sweeping National Security Law imposed on the city by Beijing in 2020 following the demonstrations. The city’s independent media have been gutted and its legislature reorganized to pack it with Beijing loyalists.Cardinal Zen, the retired archbishop of Hong Kong, is a fierce critic of China and has been blistering in his condemnation of the Vatican’s 2018 agreement with Beijing over bishop nominations, which he has said was a sellout of underground Christians in China.The Vatican spokesman, Matteo Bruni, said the Holy See “learned with concern the news of the arrest of Cardinal Zen and is following the evolution of the situation with extreme attention.”Ms. Ho also has been outspoken in her advocacy of civil and political rights. Her manager, Jelly Cheng, confirmed Ms. Ho’s arrest but said she had no other information.Mr. Hui was arrested at Hong Kong’s international airport as he sought to leave the city, Hong Kong Watch said.“Today’s arrests signal beyond a doubt that Beijing intends to intensify its crackdown on basic rights and freedoms in Hong Kong,” the group’s chief executive, Benedict Rogers, said.“We urge the international community to shine a light on this brutal crackdown and call for the immediate release of these activists,” Mr. Rogers said.Several leading Kong Kong activists have fled to Taiwan, Britain, or elsewhere, while thousands of other Hong Kongers have chosen to leave the city, raising concerns about the economic future of the Asian financial center of 7.4 million.The arrests follow the selection on Sunday of Hong Kong’s new leader, John Lee, a hard-line former security chief who ran unopposed in a process controlled by Beijing.The European Union and foreign ministers from the Group of Seven industrialized countries — Canada, France, Germany, Italy, Japan, the U.K., and the U.S. — condemned the election as fundamentally undemocratic and a betrayal of the “one country, two systems” principle under which Hong Kong was supposed to retain its own political, legal and economic system for 50 years after the end of British colonial rule.Hong Kong’s government and police had no immediate comment on the reported arrests.Human Rights Watch’s China senior researcher, Maya Wang, said she understood a fifth person, Cyd Ho Sau-lan, a former Legislative Council member, had also been arrested.Arresting Cardinal Zen for his peaceful activities “has to be a shocking new low for Hong Kong, illustrating the city’s free fall in human rights in the past two years,” Ms. Wang said in a statement.
