The police have cordoned off the entrance to Times Square in the shopping district of Causeway Bay.

There are quite a few people detained here behind the police cordon, but right now the atmosphere is relatively calm. There aren’t protesters left here - but police, journalists and passers-by.

Police rounding up protesters has become a familiar scene in Hong Kong. The difference this time is police are interested not only in protest supplies, but in the banners and flags they consider breaches of the newly enacted National Security Law. Nine people have been arrested for allegedly breaking this law.

The scenes were confrontational during the day. Calm right now, it is almost certain that some protesters will be back - despite the law. That is what today has showed.

The UK government has been raising concerns about the national security law and very publicly trying to pressure Beijing into a change of heart.

That has clearly failed – so ministers are now fulfilling their promise to allow up to three million people in Hong Kong with British National Overseas (BNO) status to come to the UK.

This is a significant move and the government wants to send a strong message.

But there will be more pressure now to rethink other elements of the UK's relationship with China – not least the deal to allow Chinese tech firm Huawei to build parts of the UK's 5G structures.

Many Conservative MPs have been lobbying against that for some time – and this will only add to their concern.

Hong Kong police say more than 300 people have been arrested as thousands gathered in protest.

Nine of those arrests were under the new National Security Law, which targets secession, subversion and terrorism with punishments of up to life in prison. Others were detained for unlawful assembly, disorderly conduct and dangerous driving.

Many people have held peaceful protests, but police have fired tear gas, water cannons and rounds of pepper balls in attempts to disperse crowds. Police also say an officer was stabbed in the arm during one arrest.

In Causeway Bay and Wan Chai, some demonstrators are reportedly digging up bricks from pavements, stacking them up as barriers or hurling them at armed police. Others have vandalised a Maxim's Cakes, a local business with links to pro-Beijing supporters.

Throughout the day, some protesters have chanted “five demands, not one less” and sung the pro-democracy anthem “Glory to Hong Kong”.

Two local journalism bodies - Hong Kong Journalists Association, and the Photographic Society of Hong Kong - have accused police of intimidating reporters attempting to cover the protests. Police have not yet publicly responded to the claims.

The new law has left many in Hong Kong anxious. Many residents are discussing scrubbing their social media of any posts that could be used against them, and there has been increased interest in secure messaging apps such as Signal, and virtual private networks.

Meanwhile, according to Google’s daily search trends, the top search in Hong Kong is currently “emigration”, while other top searches include “content of the national security law” and “full text of the national security law”.

Claudia Mo, a former journalist and pro-democracy legislator in Hong Kong, spoke earlier to Emma Barnett on BBC Radio 5 Live.

She said she was unable to answer a question on air because of the new legislation.

Lisa Nandy, foreign affairs spokeswoman for the opposition Labour party, says the security law will have a "chilling effect" on democracy.

She says the UK should "lead" on an inquiry into "police brutality" in Hong Kong.

She asks whether salary thresholds will apply to the arrangements for BNO passport holders.

In response, Dominic Raab says the home secretary will set out details of the BNO scheme in "due course".

He says it is to be expected a "large number" of those eligible for the scheme will choose to stay in Hong Kong or the wider region.

Protesters have gathered - sometimes in clusters of hundreds - despite the new threat of custodial sentences for challenging the government.

And under this security law, some of their slogans are now very dangerous to use.

Each time demonstrators chanted for Hong Kong to be liberated, the police unfurled banners that warned of potential prosecution.

They then moved in with pepper spray and water cannon. Clashes, at times, became violent. Shop windows were smashed and one police officer was stabbed.

This new law grants sweeping, open-ended powers to the authorities to crack down on any form of dissent deemed unacceptable.

It has been welcomed by pro-Beijing politicians in the city who say that last year’s protests against Chinese rule became too destructive and had to be stopped.

Protesters in Causeway Bay have been ripping up bricks from the pavement and using them to try to obstruct police vehicles.

Officers have started to clear them away, the South China Morning Post reported.

Demonstrators have also blocked roads using plastic buckets and traffic cones, police said on Facebook, and cardboard has been set on fire.

The UK government has updated its travel advice to British citizens heading for Hong Kong following the introduction of the new security law.

The Foreign Office says there is "an increased risk of detention and deportation" for those who commit an offence under the law.

"Mainland authorities could under certain circumstances detain individuals under the terms of this law, with maximum penalty of life imprisonment," it adds.

The updated advice also warns of "an increase in protests and violence" that could "occur without warning".

"You should avoid protests and demonstrations," it says.

Mr Raab spoke more about the plans to give BNO passports a pathway to UK citizenship.

He says those eligible for a BNO passport will be granted limited leave to remain for five years, during which they can work or study.

After that, they will be able to apply for "settled status" - then after a further 12 months with this status, they will be able to apply for citizenship. There will be "no quotas or numbers", he says.

He says the "special, bespoke arrangements" will honour the UK's "historic commitment to the people of Hong Kong".

Speaking before Mr Raab, Prime Minister Boris Johnson confirmed the UK would extend immigration rights for those in Hong Kong who hold British National Overseas (BNO) status.

He said the move would make it easier for people with this status to live and work in the UK and eventually get citizenship.

"We made clear... that if China continued down this path we would introduce a new route for those with [BNO] status to live and work in the UK and thereafter to apply for citizenship," he said. "That is precisely what we will do now."

Hong Kong was handed back to China in 1997, anyone born before then is eligible to apply for a BNO passport.

Around 300,000 people currently hold one, but an estimated 2.9 million people are eligible.

Mr Raab says the security law is a "flagrant assault" on freedoms of speech and protest in Hong Kong.

He tells MPs it also risks undermining the independence of Hong Kong's judicial system.

China, he adds, has "broken its promise to the people of Hong Kong under both the Joint Declaration and its own laws".

UK Foreign Secretary Dominic Raab says the imposition of the new security law in Hong Kong is a "grave and deeply disturbing step".

He says the UK considers the move a "clear and serious breach" of the 1985 Joint Declaration.

This is a legally binding agreement signed by the UK and China which protected certain freedoms in the territory for at least 50 years.

A 15-year-old girl is among the seven people arrested under the new security law, the South China Morning Post reported citing police.

The girl was detained after she was seen waving a flag carrying an independence message, it said. At least two other people arrested under the new law were also allegedly carrying pro-independence material, police said.

Promoting secession is considered a serious crime under the new law and carries heavy punishments.

Pro-democracy supporters have told the BBC they are concerned the new law takes away the "one country, two systems" form of government.

However, those supporting the new law hope it brings greater security to Hong Kong.

The Photographic Society of Hong Kong, a local media agency, has shared images on Twitter and said police were obstructing journalists from reporting on today's demonstrations.

Hong Kong Police have not publicly responded to the accusation.

Police in Hong Kong say they've arrested three woman and confiscated protest material which "[undermines] national unification".

They've shared images on Twitter of a banner and flyers calling for Hong Kong's independence, which they say violates the new security law.

The EU has reiterated its “grave concerns” about the new security law which it fears could “seriously undermine” Hong Kong’s independence.

EU foreign affairs chief Josep Borrell said the law had been adopted "without any meaningful prior consultation" with Hong Kong’s Legislative Council and civil society.

"The European Union considers it essential that the existing rights and freedoms of Hong Kong residents are fully protected," he said in a statement.

Mr Borrell said the EU was "assessing the implications of such a law and will continue to raise its concerns in its dialogue with China".

There have been clashes on the streets between police and hundreds of protesters who have gathered in areas of Hong Kong.

Demonstrators are holding a pro-democracy rally to mark the 23rd anniversary of Hong Kong being handed back to China by Britain. But authorities are clamping down, citing restrictions on gatherings of more than 50 people because of coronavirus.

Water cannon and pepper spray has been used to disperse crowds, and police say they've arrested more than 180 people. At least seven arrested were related to China's new national security law - one man was detained for holding a banner advocating for Hong Kong's independence.

Though the demonstrations are peaceful, police said one of their officers was "stabbed in the arm" by rioters during one arrest. Public broadcaster RTHK also reports that some protesters "dug up bricks, damaged buildings and smashed some windows" while chanting "Hong Kong independence".
