Senior police officials have issued a stark warning that fraudsters, increasingly leveraging artificial intelligence to perfect their deceptions, are creating an escalating threat where law enforcement is locked in a constant battle to keep pace. The future of fraud, they caution, could involve fully automated criminal schemes that require minimal human intervention.
This evolving threat is having a disproportionate impact on London. According to the City of London Police, 40% of fraud victims nationally are located within the capital. The Metropolitan Police further states that this includes 60% of all courier fraud cases.
The AI-Powered Arms Race
Oliver Little from the City of London Police told the London Assembly Police and Crime Committee that technology allows criminals to “target a much wider number of people” in what becomes “a numbers game,” while also creating barriers that obscure their true identities. He highlighted the “Hi Mum” text scam, where fraudsters pose as a family member in need, noting the potential for AI to generate realistic cloned voices from short social media clips to make such deceptions far more convincing.
“The challenge for us as law enforcement is to use technology ourselves to identify and respond. That’s the kind of the arms race that we see ourselves in,” Mr Little stated, adding that victims are often unaware AI is being used to deceive them.
Will Lyne, Head of Economic and Cybercrime at the Met, outlined the alarming progression. While fully AI-run fraud models are not yet operational, he confirmed AI is used to “optimise the scale and sophistication” within criminal business models. “We’re not saying AI is out there running fraud operations on behalf of criminals – but there is a realistic probability we’re going to get there in the future,” he told the committee.
This technological shift is supercharging fraud on an industrial scale. Beyond voice cloning, experts note that Large Language Models (LLMs) create flawless, personalised phishing lures, while generative AI can fabricate entire fake e-commerce sites. Furthermore, the rise of “fraud-as-a-service” kits is putting sophisticated tools in more criminals’ hands.
London’s Priority Fraud Threats
Against this high-tech backdrop, both rudimentary and complex scams are thriving. Rory Innes, CEO of The Cyber Helpline, noted that with just a “phone, an email account and a social media account,” criminals can cause devastating impacts, including loss of life, finances, and severe mental health harm.
The Met Police have identified six priority fraud types posing the greatest risk to Londoners, but warn that “hybridisation” – where scams blend together – makes them difficult to categorise and tackle.
Romance Fraud remains profoundly damaging. UK Finance data shows it led to over £106 million in losses nationally in 2024/25, across 9,449 reports. The average victim lost £11,222, with women and those aged 50-59 experiencing particularly high losses. Most cases originate on social media and dating platforms.
Courier Fraud disproportionately targets the elderly. Nationally, the average loss per victim exceeds £12,000, with 80% of victims over 65. In London alone, 282 offences were identified between January and July 2025.
Investment Fraud is increasingly intertwined with cryptocurrency. Action Fraud received 25,843 reports in 2024 with losses surpassing £649 million. Cryptocurrency was involved in 66% of all UK investment fraud reports last year, with UK residents losing £549 million to crypto fraud specifically. Scammers frequently use social media and even celebrity impersonations to lure victims.
Payment Diversion Fraud, such as conveyancing fraud, saw 143 cases reported to Action Fraud in the 2024/25 financial year, leading to £11.7 million in losses – an average of £78,393 per residential property transaction.
The other priority types are Abuse of Position Fraud, where someone in a position of trust commits fraud, and Card and Payment Fraud.
The Devastating Human Cost
The impact of fraud extends far beyond financial loss. Research indicates victims commonly suffer anger, severe stress, anxiety, shame, and embarrassment. Many experience a loss of trust in others, becoming socially withdrawn and more sceptical.
The psychological toll can be severe, leading to depression, suicidal thoughts, and the exacerbation of physical health conditions. Unlike victims of other thefts, fraud victims often feel gullible and responsible, a stigma that contributes to significant underreporting, particularly in cases like romance fraud.
Law Enforcement’s Uphill Battle
Facing this challenge, Mr Lyne admitted that law enforcement will “always be playing catch up,” emphasising that public education is crucial to prevention. The sector faces significant hurdles, including overstretched cybercrime units, difficulty retaining cyber-literate staff, and fragmented intelligence sharing between forces and institutions.
In response to the growing crisis, the government has committed £31 million to launch a new Online Crime Centre from April 2026, aiming to improve coordination between police, intelligence agencies, and the tech industry.
For now, the warnings from police are clear: as fraud accounts for 41% of all crime in England and Wales – approximately 4 million incidents in a year – the sophistication of the threat is accelerating, with Londoners firmly in the crosshairs.
