According to a post from the 23-year-old’s official Twitter account, he was also arrested for violating Hong Kong’s “draconian anti-mask law,” which took effect on Oct. 5 and has since been ruled unconstitutional.
“Joshua is arrested when reporting to Central Police Station at about 1 p.m. today,” the post read. “The arrest is related to participating in an unauthorized assembly on 5 Oct last year. He is told to have violated the draconian anti-mask law as well.”
The two men are scheduled for an appearance at Eastern District Magistrates Court on Sept. 30, police said.
Wong’s latest arrest adds to several unlawful assembly charges or suspected offenses he and other activists are facing related to last year’s pro-democracy protests, which prompted Beijing to impose a sweeping national security law on June 30.
Wong had been a frequent visitor to Washington, where he has appealed to the U.S. Congress to support Hong Kong’s democracy movement and counter Beijing’s tightening grip over the global financial hub. His visits have drawn the wrath of Beijing, which says he is a “black hand” of foreign forces.
Wong disbanded his pro-democracy group Demosisto in June, just hours after China’s parliament passed the national security law for Hong Kong, bypassing the city’s local legislature.
News of Wong’s arrest has been met with sweeping criticism.
“The arrest of #JoshuaWong, one of the leading figures of the #HongKong democracy movement, is yet another example of China’s attack on democracy and human rights through political persecution. #StandWithHongKong,” the World Uyghur Congress wrote on Twitter.
British lawmaker Iain Duncan Smith described Wong’s arrest as “naked political persecution.”
“Only Kafka and authoritarians will be proud as @joshuawongcf is arrested—for violating laws that themselves violate #China #Hongkong intl #humanrights standards,” Human Rights Watch China Director Sophie Richardson wrote on Twitter.
