Key Points

• Counter Terrorism Policing (CTP) London made eight arrests in connection with a series of incidents, including several arson attacks targeting the Jewish community in London.

London (Extra London News) April 21, 2026 – Counter Terrorism Policing London has arrested eight individuals in a major operation targeting a series of arson attacks and related incidents believed to intimidate the Jewish community, as announced in an official statement today.

What Led to These Eight Arrests?

As detailed in the official Metropolitan Police news release, the arrests form part of an ongoing investigation into several arson attacks in London, with seven of the eight stemming from a proactive probe into conspiracy to commit arson. The police believe the conspiracy targeted a Jewish community venue, though the exact location is not yet identified.

The timeline unfolded rapidly: On Sunday, 19 April, CTP London detectives arrested three men aged 24, 25, and 26 in Harpenden shortly after 21:00 hrs. They were taken into custody and later released on bail. As reported directly from the Met Police statement, on Monday, 20 April, a 25-year-old man was detained in Stevenage, while a 26-year-old man and two women aged 50 and 59 were arrested in a car near Birmingham. All five remain in custody at a London police station.

This morning, Tuesday, 21 April, a 39-year-old man was arrested at an address in Ealing under section 41 of the Terrorism Act 2000. This arrest connects to a separate but related CTP London investigation following the finding of jars of a non-hazardous substance in Kensington Gardens on Friday, 17 April. An ongoing search is taking place at a premises in East London.

Who Are the Arrested Individuals and What Are the Charges?

The Met Police provided specific details on the detainees without releasing full identities to protect the investigation. The Harpenden trio (ages 24, 25, 26) were held briefly before bail. The Stevenage and Birmingham group (a 25-year-old man, a 26-year-old man, and women aged 50 and 59) face scrutiny over the arson conspiracy. The Ealing 39-year-old is detained under anti-terrorism legislation linked to the Kensington Gardens discovery.

No formal charges have been announced for the latest eight, but they join a broader tally: Since the 23 March attack on Hatzola ambulances in Golders Green, 23 arrests total, with eight charged for arson offences and 13 still under investigation (in custody or on bail).

How Does This Fit into the Broader Investigation?

Deputy Assistant Commissioner Vicki Evans, the Senior National Co-ordinator of Counter Terrorism Policing, emphasised the operation’s scope in the Met Police release:

“We’ve made very clear that we will be relentless in our pursuit of anyone involved in carrying out or planning these arson attacks. Our message is clear: We will not tolerate this intimidation of our communities and will pursue those responsible. One of our key lines of inquiry is whether criminal proxies – that is to say, people being paid money to carry out a crime- are being used to commit any of these arsons.”

She added:

“While our investigations into this are still ongoing, my message to anyone even considering getting involved in this type of activity is this, the stakes are high and it is absolutely not worth the risk. When we identify you, we will seek to prosecute you. This will include considering offences under the National Security Act which comes with a significant sentence and lifetime restrictions. We will not rest until all those responsible for these acts are held to full account.”

CTP has bolstered its presence in north west London, supporting Met Police efforts to deter attacks and reassure Jewish places of worship and businesses. Evans thanked communities and urged vigilance:

“I would like to thank our communities for their support as we investigate these crimes, and would urge the public to be alert to anything which doesn’t feel right and report it to us.”

What Is the Context of the Golders Green Attack?

The investigation traces back to the 23 March assault on Hatzola ambulances in Golders Green, a Jewish volunteer emergency service. This incident sparked the wave of arrests, with CTP treating it as a hate-motivated terror case.

What Do Other Sources Report on Counter-Terror Arrests?

While the primary story centres on the Met Police arson probe, recent web searches reveal parallel counter-terrorism operations. For instance, BBC News reported on 3 May 2025 two separate probes arresting eight, mostly Iranian nationals, including five men (four Iranians: ages 29, 46, 29, 40, plus one unidentified) for plotting to target a specific premises across England (Swindon, west London, Stockport, Rochdale, Manchester).

Separately, three Iranian men (ages 39, 44, 55) were arrested in London under the National Security Act. ITV News journalist Sejal Karia detailed on 4 May 2025: Commander Dominic Murphy, head of Met’s Counter Terrorism Command, said: “This is a fast-moving investigation and we are working closely with those at the affected site to keep them updated. The investigation is still in its early stages, and we are exploring various lines of inquiry to establish any potential motivation as well as to identify whether there may be any further risk to the public linked to this matter.”

Home Secretary Yvette Cooper thanked police: “I want to thank the police and our security services for the action they have taken to keep our country safe. Protecting national security is the first duty of government, and our police and security services have our strong support in their vital work.” She noted complexity involving Iranian nationals but prioritised support for probes.

These incidents, while distinct from the Jewish community arsons, highlight CTP’s active role amid rising threats.

What Measures Are in Place to Prevent Further Incidents?

Beyond arrests, CTP is probing criminal proxies – individuals paid for crimes – and potential National Security Act violations. Searches continue at multiple sites, including East London. Enhanced patrols in north west London aim to reassure communities.

In the Iranian-linked cases, searches occurred in Greater Manchester, London, and Swindon, with police contacting the unnamed target site.

Implications for Community Safety?

These arrests underscore tensions around community-targeted violence in London. Evans stressed intolerance for intimidation, vowing accountability. Murphy urged public vigilance. No immediate public risk reported, but investigations proceed.
