The warrant allows police to detain Yang for an initial ten days of interrogation over the holding of a 3 July demonstration to demand both a moratorium on dismissal of workers and urgent action to protect lives and livelihoods during the pandemic.
The demonstration was socially distanced, participants wore masks and follow-up confirmed there was no coronavirus transmission from the event.
ITUC General Secretary Sharan Burrow said: “The proceedings against Yang, egged on by conservative media, should stop and the authorities should heed the call of workers seeking protection and support.”
