Hong Kong publishing tycoon Jimmy Lai, an outspoken critic of Beijing, and two other pro-democracy activists were arrested by police on Feb. 28 on charges of illegal assembly, local media reported.
Lai, a self-made millionaire who has been a major financial patron of Hong Kong’s pro-democracy movement, was picked up by police at his house, Cable TV and TVB News reported.
Apple Daily, one of the publications under media company Next Digital in which Lai is non-executive chairman, said he was accused of participating in an illegal march on Aug. 31.
Veteran democracy activists Lee Cheuk-yan and Yeung Sum were also arrested on Feb. 28 on the same charges, Cable TV reported.
Lai, Lee and Yeung could not be reached immediately for comment.
Hong Kong police said in a statement they would hold a media briefing on the arrests later on Feb. 28. They did not give any further details.
The arrests come after a period of relative calm in the Asian financial hub following months of intense anti-government protests.
Hong Kong saw one of its worst clashes on Aug. 31, with police firing tear gas and water cannons at pro-democracy protesters, some who threw petrol bombs.
Authorities in Hong Kong have arrested more than 7,000 people for their involvement in the protests, many on charges of rioting that can carry jail terms of up to 10 years. It is unclear how many are still in custody.
Public anger has grown over the months due to perceptions of China tightening its grip over the city. Beijing denies meddling and blames the West for fomenting unrest.
Lai was previously arrested in 2014 for refusing to leave a key pro-democracy protest site in the centre of the city. Following his arrest he resigned as editor in chief of Apple Daily. He has also come under scrutiny from Hong Kong’s anti-graft agency when they raided his home in 2014.
Hong Kong Democracy Council, a Washington based non-government organization, said on Feb. 28 that the arrests were “blatant acts of political suppression by the Hong Kong government and the Chinese Communist Party.”
The group said in a statement it was demanding the immediate and unconditional release of Lai and the other pro-democracy activists.
Mark Simon, Lai’s top aide and a senior executive at Next Digital, said on Twitter Lai, along with Lee and Yeung were “not in any way a flight risk. They need to be processed quickly and out of that police station as quickly as possible.”
