Civic groups are to host a rally outside the government headquarters in Admiralty on Thursday to commemorate the third anniversary of the pro-democracy Occupy protests. They will stand still for three minutes at 5:58pm – the exact time tear gas canisters were shot at protesters. Sound effects and steam will be used to reenact the scene. The event will be organised by Citizen Charter 617, and led by retired teacher and activist James Hon. The group have obtained a letter of no objection from the police and expect 500 people to attend.
