Police appealed to protesters this evening gathering on Tim Mei Avenue and on the footbridge to leave peacefully, as soon as possible because it is unlawful.
Officers said the meeting affected people's safety and order, impeded traffic nearby and affected the rights and freedoms of other people.
They plan to take action soon to restore order in a professional and restrained manner if protesters refuse to leave.
The Police again urged people, especially students and those who are underage, not to take part, or go near the area.
Officers also reiterated that it respects freedom of expression, speech and assembly, but people should abide by the law and maintain social order when expressing their views.
