A Hong Kong man who drove into the police with a motorcycle while carrying a flag that said “Liberated Hong Kong” was the first to be charged under the new Chinese security law for Hong Kong.

The charge is terrorism and incitement to separatism.

The law allows Chinese security officials to operate in Hong Kong openly and criminalizes many forms of criticism of the Chinese government.

Beijing passed the law this week. Critics say the security law is intended to quell the pro-democratic protests that have regularly staged Hong Kong since last year.

Police say the 23-year-old Tong Ying kit injured several officers when he ran into them on a demonstration on Wednesday.

A video shows the driver of a motorcycle knocking over some officers on a narrow street before falling over and being arrested.
