The arrest and a ban on the vigil for a second year comes as Beijing attempts to crush pro-democracy activism in Hong Kong, which has been the last place on Chinese soil where the June 4, 1989, event was publicly commemorated.
The Hong Kong Alliance in Support of Patriotic Democratic Movements of China said its vice chair, Chow Hang Tung, was arrested by police Friday morning. It is not clear why Chow was arrested, and police have yet to comment on the matter.
The alliance organized the vigil and ran the June 4 Museum dedicated to remembering Tiananmen. The museum was closed this week.
After police warned that marking the anniversary in the vigil’s usual Victoria Park venue may be illegal, Chow has continued her activism, urging people to commemorate the event privately by lighting a candle wherever they are.
Last year, thousands went to Victoria Park to light candles and sing songs in remembrance despite the ban. Police later charged more than 20 activists including Chow for their participation in the unauthorized assembly.
Two other key members of the Hong Kong Alliance — Lee Cheuk-yan and Albert Ho — are behind bars for their participation in separate unauthorized assemblies in 2019, during a period when Hong Kong saw massive anti-government protests.
Chow said in an earlier interview with The Associated Press that she was expecting to be imprisoned at some point for her activism.
“I’m already being persecuted for participating and inciting last year’s candlelight vigil,” she said.
“If I continue my activism in pushing for democracy in Hong Kong and China, surely they will come after me at some point, so it’s sort of expected.”
