Catholic Diocese of Hong Kong urged the Hong Kong government and the public to show restraint, and the administration "not to rush to amend the extradition bill before fully responding to the concerns of the legal sector and the public." Another call to "picnic" at Tamar Park on 12 June attracted close to 10,000 responses. The Legislative Council Commission issued an amber security alert. The protest zone outside the building was closed and access to the complex was limited. Sit-ins began in the morning and a large crowd built up at the
MTR exit. In the early morning hours, the crowd rushed onto
Harcourt Road and
Lung Wo Road, blocking these streets in scenes reminiscent of the 2014
Umbrella Movement protests. A banner with "Majority calls on Carrie Lam to step down" and "Withdraw the extradition bill, defend One Country Two Systems" written on it was hung from the Admiralty Centre footbridge. Around 11 am, the Legislative Council Secretariat announced that the second reading debate on the extradition bill had been postponed indefinitely.
Violent clashes Police vans carrying riot police began to line up adjacent to the
Hong Kong Academy for Performing Arts and the
Hong Kong Convention and Exhibition Centre on standby, around 1 pm. A source in the
pro-Beijing camp said that some pro-Beijing legislators were at Central Police District Headquarters, while online groups called on protesters to block vehicles that might be used to transport the legislators to the Legislative Council. . Around 3:20 pm, protesters on Tim Wa Avenue began to charge the police barricades and were doused with pepper spray in reply. Some protesters at the junction of Lung Wo Road and Tim Wa Avenue broke through the barricades and took over Tim Wa Avenue after riot police walked into the government headquarters, leaving a Special Tactical Unit to defend. Protesters also attempted to charge the Legislative Council building. Riot police dispersed the protesters by firing tear gas,
beanbag rounds and
rubber bullets. There was a stand-off on Harcourt Road between protesters and the police. Many protesters took shelter in the buildings nearby as more tear gas was fired. As of 6 pm, 22 injured people had been sent to public hospitals. At around 6:20 pm, the Legislative Council Secretariat issued a circular saying Legislative Council President
Andrew Leung had called off the meeting. Protesters remained in the streets outside the AIA Tower in
Central,
Queensway outside
Pacific Place shopping mall, and at the junction of Arsenal Street and Hennessy Road in Wan Chai into the night. In Central, private cars were employed to block
Connaught Road Central while protesters chanted slogans from the
Exchange Square bridge. Protesters defied sustained efforts by police to disperse them after nightfall. By the end of the day, at least 79 protesters and police officers had been treated in hospitals; around 150 tear gas canisters, "several" rounds of rubber bullets, and 20 beanbag shots had been fired during the protest clearance. Overnight, 2,000 protesters from religious groups held a vigil outside the government headquarters, singing hymns and praying. Various trade unions, businesses and schools also vowed to stage protests. The Hong Kong Professional Teachers' Union called for a city-wide strike lasting a week. At least 4,000 Hong Kong teachers followed the call.
Siege of CITIC Tower from Lung Wui Road. According to the CHRF, the police had earlier agreed to peaceful demonstration within the area outside
CITIC Tower in its letter of no objection. However, the peaceful rally was disrupted by the police when teargas was fired into the middle of the crowd. Videos depicting the police firing tear gas as in a pincer movement on both sides of Lung Wui Road near Citic Tower at around 4 pm went viral on Hong Kong social media. People who were trying to push into the building to flee the gas found the doors locked and themselves cornered by police. As people trickled through the jammed central revolving door and a small side door, the police fired another two tear gas canisters into the trapped crowd, fuelling panic. Protesters attempted to break down another locked side door in a desperate attempt to gain entry. Pro-democrat legislators criticised the police action which nearly caused a stampede.
Amnesty International also criticised the use of tear gas against the trapped crowd. ==Police brutality allegations==
