As we've just reported, the BBC understands that the suspect from yesterday's attack had previously been referred to the government's counter-terrorism Prevent programme.

What is Prevent?

The programme is a key part of the UK's counter-terror strategy, and places a legal duty on public bodies to identify people who may turn to extremism.

Figures like teachers, social services, faith leaders or doctors are required to refer any suspicions about people to a local Prevent body.

An assessment is then made about whether to take further action. If further action is taken, experts assess what sort of multi-agency support could benefit the individual and how best to manage risks.

Counter Terrorism Policing says the programme aims to "stop individuals becoming terrorists".

The man suspected of carrying out the knife attack in Golders Green had previously been referred to the government's counter-terrorism Prevent programme, the BBC understands.

The 45-year-old was born in Somalia, and came to the UK as a child in the early 1990s. He came legally, and is now a British citizen.

The Metropolitan Police Commissioner Mark Rowley said he had a "history of serious violence and mental health issues."

An address in south-east London is being searched.

After his arrest, the suspect was treated briefly in hospital and now remains in police custody. He is being held under the Police and Criminal Evidence Act, so can in theory he can be held for up to 96 hours if the police are granted permission by a magistrate, though that may not be necessary in this case.

Conservative leader Kemi Badenoch tells BBC Radio London's Eddie Nestor: "The community don't think that they [the government] are doing enough. I was there yesterday and you could feel the fear that was on the streets."

Earlier, the Home Office confirmed it was investing a further £25m in extra policing and security for Jewish communities.

On the funding, Badenoch says: "So we do need to see an increased police presence. The government has said it's giving money - I don't know exactly what the money is for, I don't know if that money is enough.

"But I do know that Shomrim, that community group, say that they have never had any money from government. They are having to look after themselves."

She says it was "very lucky" that police officers were close to Wednesday's attack.

The prime minister says the criminal justice system must respond in a "swift, agile and visible way" to yesterday's attack in Golders Green.

In a meeting with criminal justice agencies in Downing Street, he says there is a "duty" to quickly respond to "appalling attacks".

"A number of people have been arrested, a number are going through the criminal justice system, and it's really important that we are able collectively to demonstrate that the response will be swift and visible," he says.

Metropolitan Police Commissioner Sir Mark Rowley, Home Secretary Shabana Mahmood and Deputy Prime Minister David Lammy also attended the meeting this morning.

Keir Starmer has condemned the attack, describing it as "utterly appalling".

He adds: "There’s no getting away from the fact that this was not a one-off. This has been a series of attacks on our Jewish community, particularly in recent weeks, and there is a very deep sense of anxiety, of concern about security, about safety, about identity frankly."

In Golders Green this morning, there is still an air of anger and frustration that a second attack in the space of a few weeks has taken place here.

A Jewish man, who didn’t want to give his name, spoke to us close to the site of the second stabbing.

He said: "The UK government is not hospitable for the Jewish community. They say they are but they do nothing. I don’t feel safe walking down Golders Green high street where I’ve lived for years.

"This country is finished for Jews, people will leave to go to Israel. If my wife said she would move I would move today. I keep on begging her. In the last year, 80% of my friends have moved.

"Since the 7 October [attack on Israel] this country has gone mental. You only have to look at the pro-Palestinian rallies with over a million people gathering."

Judith, who saw the attacker yesterday and hid behind a fence, said she was devastated about the stabbings but wasn’t thinking of leaving.

She said: “I don't feel it's 1939, it's not pre-war, because the government are not promoting this. However, the government are only putting on sticky plasters: more police, very nice; more security, very nice.

"But systemically, what are they doing to stem this tide to make us the Britain that we used to be?

"What concerns me, as everybody has said, are those marches in central London that are allowed, that promote hate - but what alarms me even more are the British people who are there, because I feel they just don't know."

At 11:16 BST, police officers responded to reports of a stabbing on Highfield Avenue, which runs off Golders Green Road.

CCTV captured the suspect confront a man before chasing him down the street.

A few minutes later at 11:20, more CCTV footage shows the suspect repeatedly attacking a man waiting at a bus stop.

He was seen pushing him onto the road and out of view.

As police surround the suspect, he walks towards officers before being Tasered.

Officers can be heard yelling "drop the knife" repeatedly before he falls to the ground and is overpowered.

Shlomo, a 23-year-old who lives Hendon, saw the suspect being arrested on Wednesday.

He tells me: "I was driving when I reached the corner of Woodlands and Golders Green Road, I had to stop as a police car was blocking me.

"As I got out of my car I saw the attacker being arrested. He was 10 feet away from me, on the ground."

"I heard them saying, ‘you are under arrest for attempted murder', and I thought 'oh my goodness, what have I walked into'."

He says "the guy was big but he didn’t struggle" once police had him pinned down, but had before.

Shlomo says a paramedic arrived within seconds and asked him to help him carry his equipment, so he was close to the suspect.

"A lot of people in the street were very upset and angry and shouting at the attacker - they were heckling him," he adds. "I am quite shaken up."

"It’s been really frightening," a Jewish man from Golders Green, north-west London, tells the BBC.

Speaking to BBC Radio 5 Live, 28-year-old Joe says the Jewish community "are sharing a society with people who want to do us harm", and questions if he needs to "disguise my Jewish-ness outwardly in order to be safe".

He describes this as a "difficult question to have to ask".

A 45-year-old man has been arrested on suspicion of attempted murder after yesterday's attack.

Speaking to the BBC earlier this morning, Home Secretary Shabana Mahmood said the suspect, a British national born in Somalia, came to the UK "lawfully as a child".

Metropolitan Police Commissioner Sir Mark Rowley said the suspect has a history of serious violence and mental health issues.

Police also said they are investigating an altercation at an address in south-east London earlier on Wednesday, which is believed to involve the same suspect.

While arresting him, officers feared the suspect was carrying an explosive device and Tasered him while he continued to try to attack and stab them, Rowley said.

After his arrest, the suspect was treated briefly in hospital and now remains in police custody.

Shloime Rand's mother tells the BBC her son, the 34-year-old victim of yesterday's attack, is in "a stable condition".

"As a mother, I'm pretty horrified that these things could happen on the streets of London, in an innocent community where we try our best not to hurt anyone.

"Shloime was walking on the street minding his own business. I was able to see him yesterday. Thank God, he was conscious the whole time. We hope he will be home before Shabbat."

Reporting from north-west London

A friend of one of the victims named locally following yesterday's attack, Shloime Rand, has said the 34-year-old hopes to be home for Shabbat, the Jewish day of rest from Friday to Saturday.

They say Rand was on his way to work before the attack, adding: "He’s a sincere, quiet gentleman. A very intelligent guy."

Another man who says he knows Moshe Shine, the other victim, says the 76-year-old lives in Hendon and is originally from the Jewish community in Prestwich, Greater Manchester.

He describes Shine as "a very nice, quiet, honest person".

Mahmood then stresses that people from all backgrounds should be taking a standing against the hatred that has been projected towards Jewish communities.

"When I take the stand that I am taking against antisemitism, I am doing so as a practising Muslim, it is absolutely in line with my faith," she observes.

Mahmood goes on to say that she will personally never hesitate to say or do what she must as home secretary, but also as a Muslim, to stamp out antisemitism.

"This land is their land, it is my land too, we share this land and we must all work together to keep each other safe," she says.

With that, the home secretary's interview comes to an end.

Mahmood is asked if protests in favour of Palestinian rights could be seen as "incubating hostile views".

The home secretary says she recognises the freedom of people to protest, but says there are "far too many instances" of hate crimes being committed during demonstrations.

She adds that the crime and policing bill, which became law on Wednesday, gives additional powers to deal with repeat protests.

When asked if far-right activist Tommy Robinson's protest, set to take place on 16 May, should go ahead she says she will be having conversations with police.

She adds that she feels broader public order legislation is no longer "fit for purpose", following the Heaton Park synagogue attack last year.

Mahmood says she "will not hesitate to make further changes".

Mahmood says she recognises the Jewish community feels unsafe, and that she "completely" understands it is frustrating when there is a sense officials are "trotting out the same words" after an attack.

She describes antisemitism as "abhorrent and unacceptable", adding that the Jewish community has "every right" to live in safety.

The home secretary says attacks are intended "to divide our society", make people feel "tired and frustrated", and to erode cross-community solidarity.

Asked about policing, Mahmood says "we are straining every sinew in terms of our security posture here", and points to the £25m in funding announced today - but says it is "not the only answer".

The home secretary is asked if she agrees with the government's adviser on terrorism, Jonathan Hall KC, that the recent attacks on Jewish people in the UK are "the biggest national security emergency" in almost a decade.

"I am treating this as an emergency," she tells the BBC.

But she says that the phrase "national emergency" has particular connotations, for instance suspending elements of democracy.

"That is not quite where we are," she notes, but stresses this is the top security issue that she is dealing with.

We're now hearing from Home Secretary Shabana Mahmood, who is asked on BBC Radio 4's Today programme about claims from a group possibly linked with Iran that it was responsible for the attack in Golders Green.

She says it is "not unusual" for such groups to claim responsibility for such attacks, but the background and motivation of the attack is still being investigated.

Harakat Ashab al-Yamin al-Islamiya (Hayi), which translates as The Islamic Movement of the People of the Right Hand, is claiming it was behind the attack in Golders Green - although it has not provided any proof.

The BBC understands that counter-terrorism investigators know about the claim - but this is where we have to be cautious. The claim could be opportunistic, writes our home and legal correspondent.

The shadow home secretary has called for increased use of counter-terrorism surveillance techniques to identify and prevent antisemitic crime.

Chris Philp, who was minister for crime and policing from 2022 to 2024, tells BBC Breakfast the UK also "urgently" needs more police patrolling Jewish communities to deal with a "relentless increase" in attacks.

Figures show a large spike in antisemitic crime in recent years, peaking in 2023.

Philp says the UK is "importing antisemitism" via immmigration, adding: "I think people who are here who are foreign citizens with antisemitic views, or who support extremism or terrorism, should frankly be deported."

Mahmood says she has full confidence in Met Police Commissioner Mark Rowley, and praises the police's efforts to tackle the recent spate of attacks against Jewish communities.

The home secretary is repeatedly pressed on comments from Chief Rabbi Ephraim Mirvis yesterday, who told the BBC people in the UK who are visibly Jewish are no longer safe.

Mahmood says she understands there is fear in the community, but repeats that the government is putting more policing and security in place "so that people can go about their business".

Mahmood says she accepts that security can only tackle the "end of the problem", and more must be done to address racism "at its root".

The 45-year-old suspect arrested yesterday came to the UK "lawfully as a child" from Somalia, Home Secretary Shabana Mahmood tells BBC Breakfast.

Yesterday police said he was born in Somalia but did not indicate how he arrived in the country.

Mahmood says she can't give further details while the investigation continues.

The government has announced an extra £25m in funding for increased police patrols and security in Jewish communities after Wednesday's attack in Golders Green.

It says the funding will also be used to put further protections in place around synagogues, schools and community centres.

We're expecting to hear from Home Secretary Shabana Mahmood shortly and will bring you more.
