In Mong Kok, thousands of people have flooded Nathan Road and Argyle Street where the police presence is low. Elsewhere, thousands of students have gathered at Chinese University in Sha Tin where discussions are being held over the continuing class boycott. The Federation of Students has called for a general strike to begin on Monday. 2.50am: Extraordinary scenes in Mong Kok where a small group of police officers has been surrounded by hundreds of protesters, who raised their hands in the air to show that they were not going to attack or charge the officers.

"I came out after seeing on TV police use tear gas. I am so shocked and angry. They can't do this to the people. I must come!" said Kwok. "If police come, I will retreat, but I won't go home," she said, stressing that she does not belong to any organisation and came on her own initiative.

Riot police rushed into the crowd but halted when protesters raised their hands to show that they did not intend to fight back. 1.46am: In a recorded speech posted on the government's website, Chief Executive Leung Chun-ying urges protesters to peacefully disperse as soon as possible "so that the daily lives of the public would not be affected".

He also called on the organisers of Occupy Central to stop the movement "in the interests of society". Meanwhile, in Causeway Bay...

Here is the scene at the junction of Nathan Road and Argyle Street in Mong Kok. 1.10am: Anson Chan Fang On-sang, Hong Kong's former No.2 official, says in a statement: “This is a sad day for Hong Kong. Pictures of our police force firing pepper spray and tear gas into the faces of unarmed protesters will shame our government in front of the whole world. We strongly condemn the government’s action. By not fighting for the aspirations of the community for genuine universal suffrage our government has paved the way for the current crisis. What we need now is leadership and accountability, not violence and repression.” 12.51am: The scene in Causeway Bay, a busy shopping and business district, just after midnight. 12.45am: Hundreds of protesters have erected barricades and are staging a sit-in on Hennessey Road in Causeway Bay.

"We do not want to see anyone get hurt. A victory with sacrificed lives is not a victory," Zen said. "Today we have sent out a very clear message ... [but] we have witnessed an irrational regime. Please go home! There's nothing we can talk with [the government about]." Cardinal Zen at frontline: let us sing the last song and go back home. You have already won the battle. #OccupyCentral pic.twitter.com/A7YkoUhCZU — Jeffie Lam (@jeffielam) September 28, 2014 11.15pm: Occupy Central co-organiser Dr Chan Kin-man says the protesters should retreat. "It is a matter of life and death," Chan said. "We put people's safety as our top priority. "Retreat doesn't mean giving up.. we will still continue to struggle." He says it's hard for Occupy Central to control the crowd outside as the occupation was self-initiated. "Occupy Central has succeeded as long as the democracy spirit never dies." 11.14pm: Pan-democratic politicians Emily Lau Wai-hing, Albert Ho Chun-yan, Fernando Cheung Chiu-hung, Yeung Sum and scholar Joseph Cheng Yu-shek were released by police at about 10pm, according to the Democratic Party.

They are now standing off against 20 officers guarding the main door to police headquarters. 10.20pm: Many people say television footage showing police firing tear gas at unarmed students prompted them to leave their home and join the Admiralty crowd. Michelle Chow, 53, said she was shocked the police used violence against peaceful students who kept their hands above their heads. "How could the police say the students were crashing against you when you were in fact pushing forth against them?" said Chow, who came in the evening. "It's my civil responsibility to show support for the students. The government must be scared if it uses such irrational force." Kenneth Kwok, 23, an IT worker, said he decided to come after seeing the first tear gas shot. "It's necessary for Hongkongers to stand united and support these non-violent students against excessive force," he said. "You can tell how irresponsible the government is by evading the public after all these people came out." Colby Lee, a 20-year-old student, said he felt an urge to come after seeing the tear gas shots. "The turnout matters. No one knows what the police will do if there aren't more people coming," he said. 9.55pm: Police fire tear gas canisters onto Connaught Road Central near City Hall.

PTU is extremely angry and strongly condemns the SAR government’s and police’s crazy actions.” 8pm: The Executive Council (Exco) has issued a statement: The Exco non-official members appeal to members of the public to cherish the safety and stability of the Hong Kong Special Administration Region and not to participate in any illegal activities of the "Occupy Central" movement. Members also call on members of the public to seize the opportunity of the second phase of the public consultation on constitutional development to fully express their views. If people of Hong Kong can seek common ground while respecting our differences, we can achieve the shared objective of electing the Chief Executive in 2017 by universal suffrage. 7.57pm: The Federation of Students urged all protesters to leave the scene if the police fire or use a long range acoustic device known as a sound cannon.

He was sitting next to the escalator on Harcourt Road when the tear gas was fired. "My eyes hurt so badly and my lungs were burning," he recalled, after tear gas was fired. "Police have used excessive force today," he said. 7.41pm: The government confirms that there was a mix-up over a police banner spotted in Harcourt Road during clashes that warned officers would fire if protesters did not disperse. A government spokeswoman confirmed that the warning was that police would fire tear gas, not bullets. The spokeswoman added that ordinary police officers who took part in operation did not carry guns while riots police officers had plastic bullets loaded in their guns. “But not a single plastic bullets had been fired so far,” the spokeswoman said. 7.30pm: Protester Kenneth Wong, 25, stood in front of some 10 police officers at the car park entrance next to the Civic Square. "I want to tell them they are Hongkongers as well, and they also have choice," he said. "While they could put on mask before firing tear gas at people, I'm standing here, without any mask, to tell them they are doing something wrong. I have no fear." Meanwhile, the Hong Kong Professional Teacher’s Union announces that it will go on strike on Monday to protest the police’s “brutal handling” of the protests. 7.20pm The MTR Corporation announces that trains will skip Admiralty Station tonight. 7.13pm: Hong Kong Human Rights Monitor condemned the police’s crackdown on protesters. Its director Law Yuk-kai said it was “an unprecedented deviation of normal police practices". Law said the crackdown was unnecessary because protesters were only exercising their basic human rights for a peaceful demonstration. He went on to say that the SAR government has turned into a “totalitarian regime". “The way police crackdown on protesters was not proportionate.” 7.09pm: Chu Kai-lun, 31, claimed he was tricked by police. "A senior inspector told us to sit down, saying they won't do anything," he said, adding moments later police pulled on their gas masks and launched a volley of gas. The Hospital Authority says it expects a lot of people will need medical treatment due to the Occupy protests. It says waiting times at the three public clinics at Queen Mary Hospital, Ruttonjee Hospital and Pamela Youde Nethersole Eastern Hospital will be longer than usual, asking people to be patient. More volleys of tear gas are being fired onto Harcourt Road. Watch: Police use pepper spray and water guns as protesters outside government office tried to rush in 7pm: Riot police in green uniforms are carrying what appear to be shotguns that may fire rubber bullets. Another volley of teargas has been fired into the crowds. Each time tear gas is deployed crowds disperse for a while and then return to re-occupy the same space. Leung Yiu-hei, 17, said: "People on both sides of the Harcourt Road tried to run away after the first shot was fired. The second shot was then fired quite close to me, and I saw someone tried to cover it with a towel and poured water over it," he added. "We didn't launch any attack at the police. What we have are our bare arms.I don't know how these - Police using batons and tear gas - could ever happen to Hong Kong," he said. 6.47pm: The federation of students is now calling on protesters who have retreated to Tamar Park to go back and protect the stage outside Civic Square. 6.41pm: Eric Lai, 27, was near the Admiralty Centre when tear gas was fired. E said he was not wearing protective goggles and had felt the effects of the gas. After that, he joined protesters on Queensway. "Don’t let my look fool you, I am really scared.,” he said. He said he wanted all Hong Kongers and also those outside the city to witness the movement. His friend Felix Tang, 25, said he only started to join pro-democracy protests after Leung Chun-ying became chief executive in 2012. "No one even guessed the police would be so violent. We are unarmed, we only have our hands," he said. The two were expecting tear gas to be fired on Queensway too, but said they would stay as long as possible. "Even if you know you are not going to succeed, it is wrong to stop trying," Tang said. Alvin Lai, a 23-year-old university graduate, said the force deployed by the police shocked him. He was sprayed with pepper spray outside government headquarters. "Today’s protest is not particularly fierce. I thought things would be OK as long as a lot of people were here," he said. "People can’t even stand pepper spray. Why use tear gas and threaten to shoot?" 6.38pm: Occupy Central organisers take to the the stage and call on protesters to retreat from Harcourt Road and Tim Mei Avenue to Tamar Park. Equipment and materials belonging tp Occupy have also been moved to the park. 6.28pm: The Federation of Students sets a midnight deadline for the Hong Kong government and the national governments to meet their demands, otherwise, they would escalate their actions by boycotting classes indefinitely.

Retract the NPC standing committee decisions on August 31. 3. Reopen "Civic Square" to the public. 4. Allow public nomination for the 2017 chief executive election. 6.15pm: Genny Ying ws among the hundreds of protesters who retreated from Civic Square to Tamar Park after police fired tear gas. "It never occurred to me that tear gas would be used in Hong Kong until we’re briefed how to handle it once tear has is fired," said the 24-year-old who retuned to Hong Kong recently after finishing her degree programme in Melbourne. "But it wasn’t really that surprising as I read on Facebook some time ago that police already purchased anti-riot weapons such as the sound cannon." "I can’t imagine what it would be like if [sound cannon is used] and thousands of people throw up at once." 6pm: Police fire as many as six rounds of tear gas into Harcourt Road and launch baton charges on the crowd. Protesters scatter hundreds of yards, many heading towards the harbourfront as they leave the protest zone via the Legco exit. Most protesters have retreated to Tamar Garden.
