173 arrests in Croydon, and a watchdog that could take police to court over it
What happened
On 4 November 2026 the Home Office announced that it will put police use of facial recognition on a proper legal footing, with a new watchdog that can take forces to court if they break the rules. At the moment, the rules covering this technology are spread across different pieces of law. The government describes the current position as a fragmented system, and says it needs replacing with a clear, consistent set of laws. Five things were announced. There will be a new independent watchdog overseeing police use of this and future technologies. It will be able to advise on standards, scrutinise forces, and recommend action to ministers. If a force refuses to comply, the watchdog can pursue enforcement, including applying for a court injunction that bars the force from using the technology at all. Any technology used by law enforcement will have to be rigorously and independently tested for bias or discrimination based on age, gender or race. A specific law will require police use of facial recognition to be intelligence-led and proportionate. It may only be used where officers believe wanted people could be present in an area. A new legal code of practice will set standards all forces must follow, developed with the new regulator. A separate legal code will cover businesses, including shops, that use facial recognition to tackle crime. The announcement follows a public consultation, which the government says showed strong public support for the technology alongside a need for tighter limits on how widely it is used. Home Secretary Shabana Mahmood said: "Facial recognition technology has been the biggest breakthrough for catching criminals since DNA matching." She said the benefits are clear, but that use must be fair, safe and proportionate.
Why this matters
Live facial recognition works by scanning the faces of people walking past a camera and comparing them, in real time, against a list of people the police are looking for. If there is no match, the system is designed to discard the image. That means it is different from almost every other police tool. A fingerprint check or a DNA test happens to a specific person for a specific reason. Facial recognition scans everyone who walks past, and most of those people have done nothing wrong and are not suspected of anything. That is why the legal framework matters more than the technology itself. The question is not only "does it catch criminals?" but "what are the limits, who enforces them, and what happens if a force goes too far?" Until now, the honest answer to that last question has been unclear. The ability to seek a court injunction stopping a force from using the technology is a genuinely sharp power, and it is the part of this announcement that changes the balance most. The independent bias testing matters too. Early facial recognition systems in various countries were measurably less accurate for women and for people with darker skin. If a system is wrong more often for some groups than others, then the burden of false matches - being stopped, questioned, asked to prove who you are - falls unevenly. Requiring testing by law, rather than by goodwill, is the difference between a promise and an obligation.
What the evidence actually says
The government published specific figures, and they are worth separating into what they do and do not show. In Croydon, static live facial recognition cameras ran from October 2025 to March 2026 and led to 173 arrests, including people wanted for rape, kidnap and sexual assault. Over the same broad period, a Metropolitan Police report found overall crime in Croydon fell by 10.5% compared with the previous year, and offences linked to violence against women and girls fell by 21%. At this year's Notting Hill Carnival, police used the technology to stop 86 registered sex offenders, and seven were arrested for breaching civil orders or notification requirements. Here is the careful bit. The 173 arrests are a direct result of the cameras - that is a clear, countable figure. The 10.5% fall in overall crime is not the same kind of claim. Crime rates move for many reasons at once, including more officers on the street, changes in reporting, and wider trends. The figures sit side by side in the announcement, but one does not prove the other. Treat the arrest numbers as solid and the crime-rate figures as context. On accuracy, the Home Office says it independently tested a new retrospective facial recognition algorithm - used to compare images after an event rather than live - and describes it as highly accurate and unbiased. Forces can roll it out from next year. The algorithm used in live recognition vans has also been independently tested. On money, £11 million has been committed to triple the number of live facial recognition vans available to police in England and Wales. And here is what the announcement does not contain: timelines. There is no date for when the watchdog will exist, when the new laws will be passed, or when the codes of practice will come into force. That is a significant gap. Until the legislation is actually passed, these are commitments rather than rules. The announcement also quoted figures and views from a range of people, including Neil Basu QPM, a former head of Counter Terrorism Policing, who said that having a human officer make the final decision is key, and Dal Babu, a former Metropolitan Police Chief Superintendent, who welcomed the engagement with the public. Sue Daley of techUK said clear, consistent regulation is crucial for long-term public support.
Practical advice
Know what you are looking at. Police forces using live facial recognition are expected to signpost it, usually with marked vans and signs nearby. If you see one, the system is scanning passing faces against a specific watchlist. You are not obliged to walk through it. Avoiding a facial recognition camera is not in itself grounds for suspicion, and courts have recognised that. Equally, if officers have separate reasons to stop you, those reasons still apply. If you are stopped after a match, ask whether it was a facial recognition match. Ask for the officer's name and number, and the reason for the stop. You are entitled to that information, and it matters if the match turns out to be wrong. If you believe you were wrongly matched, you can complain to the force directly, and you can escalate to the Independent Office for Police Conduct. You can also make a subject access request under data protection law to ask what personal data a force holds about you. For shops and businesses: a separate legal code is coming for private-sector use. If your business already uses facial recognition, or is considering it, this is the moment to review it rather than after the code lands. Current data protection law already applies, and the Information Commissioner's Office publishes guidance on biometric data. Keep an eye on the legislation rather than the press release. The protections described here only become real when they are law, and no date has been given. If this matters to you, the Bill's progress through Parliament is the thing to watch - and you can write to your MP while it is still being debated, which is a far better moment than after it passes.
What to know
The government will create a single legal framework for police facial recognition, replacing rules currently scattered across different laws. A new independent watchdog will oversee it and will be able to seek a court injunction barring a force from using the technology if it does not comply. All law enforcement technology of this kind will have to be independently tested for bias based on age, gender or race. Police use will have to be intelligence-led and proportionate, and only where officers believe wanted people could be present. Two new legal codes of practice will follow, one for police and one for businesses. The supporting figures: 173 arrests from the Croydon deployment between October 2025 and March 2026; 86 registered sex offenders stopped at Notting Hill Carnival with seven arrests; £11 million to triple the number of live facial recognition vans. The important caveat: no timelines were given for the watchdog, the laws or the codes. These are intentions until Parliament passes them.
