Hong Kong police arrested nearly 100 children in more than 390 protesters against the controversial security bill and the national anthem bill.

Hong Kong police on May 27 and May 28 operated in many counties to prevent protests against two controversial bills.

The Hong Kong Education Office said on Thursday that it had recorded many cases of young people being arrested while wearing uniforms, saying it was "extremely heartbreaking and disturbing".

Hong Kong protesters in recent days repeatedly took to the streets to protest the security bill and the Chinese anthem bill.

The resolution to build the Hong Kong security law was passed by the Chinese parliament (NPC).

Meanwhile, the Chinese national anthem bill is about to be discussed for the third time and may be passed next month.
