On June 12, thousands of protesters blocked major roads surrounding Hong Kong's government headquarters and legislature in the Admiralty district to prevent government officials from presenting amendments to a controversial extradition bill . The secretary of the Legislative Council announced that the scheduled session at 11:00 am would be deferred until further notice after lawmakers were unable to reach the Legislative Council Complex.
Just after Sunday's million-strong protest, the HK gov announced it would continue to push the #extraditionbill . The parliament is to debate it today & this is the people's way of stopping it.

The roadblock protests followed a June 9 rally where over a million people took to the streets  against proposed amendments to the Fugitive Offenders and Mutual Legal Assistance in Criminal Matters Legislation (Amendment) Bill . The proposed bill would provide legal grounds for the Chief Executive and local courts to handle case-by-case extradition requests from authorities in mainland China, Taiwan and Macau. Protesters believe that the amendments would make it easier for mainland China to arrest critics, dissidents, and even journalists in Hong Kong.
Soon after the rally, the government issued a statement stressing that the administration will continue to proceed with the second reading of the bill on June 12. The government's hard-line stance triggered a round of violent clashes  between the police and hundreds of young protesters who gathered outside the Legislative Council on June 10.
The police arrested 31 protesters and took records of the identity of 358 protesters who stayed overnight after the rally. About 80 percent of them  are between 16 to 25-years-old.
On June 10, Chief Executive Carrie Lam continued defending the bill and stressed Hong Kong is “duty-bound to address that deficiency”.  The president of the Legislature, Andrew Leung, decided that Hong Kong lawmakers would have to vote on  the controversial bill by June 20.
The organizer of the Sunday rally, Civil Human Rights Front, called for another round of protests  outside the government headquarters to paralyze the government starting on June 12. Student unions from seven Hong Kong tertiary institutions, including Chinese University and Baptist University, have called for students to boycott classes and join the rally. Over a hundred Hong Kong employers  from across industry sectors have pledged to either suspend business or support employees who choose to strike.
About 2,000 protesters gathered overnight outside the Legislative Council on June 11 and more protesters joined them the next morning. At around 8:00 am, thousands of protesters occupied major roads (namely Lung Wo Road and Harcourt Road) surrounding the Legislative Council Building.

Although the protester's blockade was able to push back the scheduled session on the morning of June 12, house rules allow the Legislative Council president to resume the meeting with only one hour's notice.
