Crimestoppers’ unmarked office in a London suburb hums with quiet urgency. Agents field up to three thousand anonymous reports each day, turning worried calls and online forms into roughly eight hundred nuggets of intelligence for police forces nationwide. In the last twelve months those tips have helped solve or prevent at least 35,791 offences, a figure the charity believes is only the tip of the iceberg.
“It’s kind of an insurance service for society in many respects,” chief executive Mark Hallas, a former head of intelligence and security in the army, tells The Update Desk. “Sometimes one tiny bit of information can be the difference between life and death, between a massive result or not.”
Origins of a silent lifeline
Founded in 1988 by Lord Michael Ashcroft, Crimestoppers grew out of the murder of PC Keith Blakelock during the Broadwater Farm riots in Tottenham. Blakelock was stabbed amid clashes between residents and the Metropolitan Police, leaving many witnesses too fearful to approach officers directly. Ashcroft, together with then Met commissioner Kenneth Newman and Lord Peter Imbert, asked how to reach those who wanted to do the right thing but would not speak to police.
The charity was loosely modelled on a 1976 initiative from Albuquerque, New Mexico, beginning as a simple phone line called the Community Action Trust. Over almost four decades it has evolved into the organisation that today supplies law enforcement with hundreds of thousands of arrests’ worth of intelligence.
The Sarah Everard effect
Public trust in policing took a sharp hit after the kidnapping, rape and murder of 33‑year‑old marketing executive Sarah Everard in March 2021. Serving Metropolitan Police officer Wayne Couzens, who used his warrant card to lure her into his car, received a whole‑life order for the crime.
“I think trust and confidence in policing has taken a bit of a hit,” Hallas adds. “So whilst that might not be great for society as a whole, it has meant that I think a lot of people kind of channel shifted and come across to us because they know that they contact us safely, securely, and above all else anonymously.”
Since then, Crimestoppers has launched a nationwide Police Anti‑Corruption Abuse Reporting Service, and the number of reports passed to law enforcement has more than doubled in a decade – over 250,000 in the year to March 2026, drawn from more than 827,442 total public contacts. Growth has accelerated fastest in the past five years, a trend the charity links partly to the “Sarah Everard effect”.
Inside the call centre
Louise Peers, who has led the contact centre for two decades, describes a climate of deep suspicion toward police. “People just don’t want to speak to the police, even so far as they don’t want to phone 101,” she says. “They don’t want to speak to police staff. They don’t want to be recorded. You know, they don’t want to engage at all, and they will actively avoid that.”
The team handles a 73 percent year‑on‑year surge in time‑critical reports – information about crimes in progress, threats to life, or serious safeguarding concerns. Peers recalls one harrowing shift: “I personally remember where someone was watching an incident from the bedroom window,” she says. “In the end the agents were on the phone to the person, on the phone to the police, and we’re trying to protect the source because they were so scared that someone would a see them at the window on the phone, or blue lights would turn up at their door looking for a statement.”
Unlike many call centres, Crimestoppers offers no canned scripts. Handlers build rapport with callers to extract the best possible detail. Although the charity is famed for cash rewards, only a tiny fraction are ever claimed. “It is not and has never been the motivating factor,” Peers says, adding that most callers never ask for the money.
Anonymity is built into every layer of the system. Phone numbers are scrambled, IP addresses cannot be traced, and handlers never learn the identity of the informant. Peers stresses this point: “What is most import, Ms Peers says, is their unwavering commitment to anonymity. When you contact Crimestoppers, phone numbers are scrambled and IP addresses cannot be traced so the handlers can never identify the source of the information. ‘Everything is designed within an inch of its life to be anonymous,’ she says. ‘I have had interactions with, you know, counter terrorist policing saying this is national security. You will give me that person’s number. But I don’t have it. Network providers don’t have it. And then, if you don’t mind, let me just take a second to say that you probably have this piece of intelligence because we can’t get that. ‘Whatever reason any agency needs that source detail, we genuinely cannot get it.’”
Reaching younger voices and hidden harms
The charity’s youth arm, Fearless, is becoming a vital tool in the fight against knife crime. Research shows that only 31 percent of 16‑ to 25‑year‑olds would be very likely to tell police someone is carrying a knife, but that figure rises to 51 percent when reporting is anonymous.
“We all know, you know, young people that kind of issue about we don’t we don’t snitch, we don’t want to dob our friends in, and I think you’ve got to turn the narrative on its head,” Hallas explains. “And it’s not about those things. It’s about protecting your community. It’s about preventing something potentially very serious taking place.”
Callers are also increasingly using the service to flag hidden harms such as domestic abuse, child neglect, female genital mutilation and modern slavery. Often the informant is one step removed – a sister, coworker, neighbour or friend who witnesses coercive control or other abuse but feels unable to approach officers directly.
Why it Matters
The surge in anonymous tips reveals a stark shift in how the public seeks safety when faith in official channels wanes. By providing a secure, untraceable route for information, Crimestoppers not only helps solve crimes but also offers a lifeline to communities that feel abandoned by the police. In an era where trust is fragile, the charity’s model demonstrates that anonymity can be a powerful force for justice, empowering ordinary people to become extra eyes and ears for society without fear of reprisal.
