The Hong Kong authorities are preparing to conduct a chaotic day on the streets of the city on Tuesday, the 70th anniversary of the founding of the People's Republic of China. Metro stations and shopping centres will be closed before the protests, fearing that this may turn into violence.

Tse Chun-Chung, chief administrative officer of the Police Public Relations Office, said at a news conference on Monday that this would be a "very serious violent attack."

Police said that a number of major roads will be closed near the Hong Kong Convention and Exhibition Centre on Tuesday, where a flag-raising ceremony will be held at the conference centre.
