Hong Kong activist Joshua Wong was sentenced Monday to 3 months in prison for breaching court bans on disclosing personal information about a police officer during 2019 anti-government protests.
An elections official said the pro-democracy activist's call for "self-determination" in the Chinese territory was inconsistent with pledging allegiance to the city and its constitution.
The group Demosisto said Agnes Chow and Joshua Wong were arrested early Friday morning. Police also confirmed the arrest of activist Andy Chan.
If found guilty, the protesters reportedly could face up to 10 years in jail. Demonstrations began several weeks ago over an extradition bill and have grown to include other demands.
Demonstrators flooded the arrivals terminal, taking their demands for protection of Hong Kong's freedoms to an international audience.
"Hello world and hello freedom," said the activist, who served a month on a contempt of court charge. Wong called on Hong Kong's leader to resign after protests over a controversial extradition bill.
