The national security trial of Hong Kong's now-defunct Tiananmen vigil group has been adjourned to May for closing statements, with activist Chow Hang-tung again barred from referring to the 1989 'massacre'.

A former leader of a now-defunct Hong Kong group that organized annual vigils for the Tiananmen crackdown told a court that the group feared the national security law could be used for political suppression.

A former leader of a now-dissolved Tiananmen vigil group has testified in court that their published writings were intended to expose Hongkongers to democratic movements in mainland China, not to incite subversion. This testimony comes as a Hong Kong barrister and activist, Chow Hang-tung, is also on trial for allegedly inciting subversion, criticizing Beijing for undermining the nation's constitutional order.
