On 9 June 2019, a historic 1.03 million people took to the streets of Hong Kong to oppose the amendments to the Fugitive Offenders Ordinance (also known unofficially as "extradition law amendment bill (ELAB)"), yet the government made it clear that night that it would continue the Second Reading debate in the Legislative Council. Tens of thousands of people took to the streets on 12 June, surrounding the Central Government Offices and the Legislative Council in Admiralty, in an attempt to stop the passage of the amendment. At around 3 pm, the police dispersed protesters by force, using 240 tear gas canisters, 19 rounds of rubber bullets, 3 rounds of bean bag rounds and 30 rounds of sponge grenades. On 16 June, a historic 2 million people took to the streets again to oppose the draconian law amendment, and police brutality.

Following the anti-extra bill march on 21 July 2019, a group of white-clad men clad men indiscriminately attacked civilians in Yuen Long.

Protest arising from the amendment of the extradition bill in Hong Kong has continued for six months since June 2019. On August 31, 2019, with protests taking place in different parts of Hong Kong, police entered Prince Edward MTR Station at night to hunt down protesters and attacked passengers on platforms and train cars.
