A large protest broke out in Hong Kong as the Legislative Council attempted to pass a bill which would make it illegal to insult or abuse to Chinese national anthem.
Hong Kong does not have its own anthem so the Chinese anthem is sometimes played, but it's frequently booed due to tense relations between the island and the mainland.
If it becomes law, anyone who mocks the anthem would face a fine of up to $10,000 and three years in prison.
But protests forced Thursday's debate to be suspended as the legislature descended into chaos.
One pro-democracy lawmaker Eddie Chu Hoi-dick managed to evade security staff before others were removed from the council chamber.
The first to be removed told reporters: "We have wanted to use any method to stop this national anthem law getting passed by council".
The disruption to lawmakers follows a day of protests outside with Hong Kong police firing pepper pellets at protesters and making hundreds of arrests.
Those detained were mostly young, some dressed all in black, some in office clothes, and some girls were in school uniforms.
And protesters have another big concern, Beijing is planning the introduction of a security law, which they fear will strip Hong Kong of basic freedoms.
This comes after the US Secretary of State Mike Pompeo delivered a major blow to Hong Kong saying it no longer merited special treatment under United States law as it was no longer autonomous from China.
If that special status was removed, it would jeopardise billions of dollars worth of trade, not only for Hong Kong, but for mainland China too.
