Police arrested a man at the Hong Kong International Airport in early hours of Thursday after he allegedly stabbed an officer at an unauthorised protest.
The man in his early 20s was arrested on a UK-bound Cathay Pacific flight, according to police sources cited by local media.
The force said a riot police officer was stabbed with a short knife near Hing Fat Street in Causeway Bay at around 4 pm on Wednesday, as crowds defied a gathering ban following the enactment of sweeping national security legislation.

The officer was attempting to detain another individual when the incident occurred. The attacker fled the scene afterwards. Police accused “rioters” of assisting the alleged assailant to escape.

Throughout the day thousands took to the streets in Causeway Bay and Wan Chai to oppose the newly-enforced legislation, criminalising secession, subversion, foreign interference and terrorism. They chanted Hong Kong independence slogans and waved protest flags, despite police warning their acts could violate the new law.

Police deployed water cannon, tear gas, pepper spray and pepper balls to disperse crowds. As of 10 pm on Wednesday, police made around 370 arrests in the area, with ten people apprehended for breaching the national security law.
A 23-year-old man was taken into custody after he allegedly drove a motorbike – sporting a flag with protest slogan “Liberate Hong Kong, the revolution of our times” – into three policemen in Wan Chai at around 3.30 pm. He was arrested for “furious driving” and violating the national security law.
Also on Wednesday, a man with a protest flag failed to stop at a police cordon, leaving several officers injured as they apprehended him. The 23-year-old was arrested for alleged “furious driving,” according to police. https://t.co/5JZKqP5Jsq pic.twitter.com/M9qs1XeL90
