Avon and Somerset Police have forfeited £1,032,487.86 in Bitcoin, other crypto assets and cash from a deceased man previously convicted of money laundering, the force’s largest cryptocurrency seizure since wallet-freezing powers took effect in April 2024.
The force said the assets were traced to darknet marketplaces that operated between 2016 and 2019 and have since been shut down by law enforcement.
Crypto seizure targets darknet wealth
The latest crypto seizure represents the largest cryptocurrency recovery recorded by Avon and Somerset Police since crypto wallet freezing orders were introduced in April 2024.
Under the UK’s strengthened enforcement framework, authorities can freeze cryptocurrency where there are reasonable grounds to suspect that the assets are connected to criminal activity.
The case subsequently proceeded under the Proceeds of Crime Act, with a court determining that the assets represented proceeds of unlawful conduct.
The significance of the crypto seizure goes beyond the £1 million valuation. Investigators used specialist cryptocurrency tracing and financial investigation techniques, supported by the force’s Cyber Team, to follow blockchain transactions back to darknet marketplaces.
Those marketplaces were associated with criminal activity including drug supply and people trafficking, according to police.
Crypto seizure shows blockchain is no safe haven
The case delivers a powerful warning to criminals who still assume cryptocurrency automatically provides anonymity.
Detective Constable Anthony Davis of Avon and Somerset Police’s Financial Investigation Unit said the investigation demonstrated the growing importance of specialist financial-investigation skills in recovering crypto-linked criminal assets.
“Many people think cryptocurrencies provide anonymity, help conceal wealth and place assets beyond the reach of law enforcement,” Davis said.
“In reality, a permanent record of transactions is stored on a digital ledger called a blockchain, which can be an invaluable source of evidence.”
That permanent transaction history is becoming increasingly important to modern crypto seizure investigations.
Rather than eliminating an investigative trail, public blockchains can preserve transaction histories that investigators can analyse alongside exchange records, financial information and other evidence.
Davis added that the force would continue using available powers to identify, trace and recover criminal property “regardless of the form it takes.”
Crypto seizure cash could return to communities
The financial impact of the crypto seizure will not end with the court forfeiture.
Avon and Somerset Police said funds recovered through the Proceeds of Crime Act are reinvested into community and policing initiatives.
The recovered money can support education and training, early intervention and crime-prevention programmes.
That creates a striking reversal: cryptocurrency allegedly connected to criminal activity is being transformed into funding for programmes designed to prevent crime.
Crypto seizure wave is spreading across UK
The Avon and Somerset case is part of a broader UK push to follow cryptocurrency through sophisticated criminal networks.
In July, the Metropolitan Police announced that three men had been jailed after impersonating police officers to defraud eight victims of more than £4 million in cryptocurrency.
Investigators combined blockchain transactions, communications, financial records and cryptocurrency-exchange information to identify the network and trace the stolen assets.
The Financial Conduct Authority has also intensified enforcement. In April 2026, the FCA worked with HM Revenue & Customs and the South West Regional Organised Crime Unit to target eight London premises suspected of illegal peer-to-peer crypto trading.
The message from these operations is increasingly difficult for criminals to ignore: crypto seizure is becoming a sophisticated investigative tool rather than an emergency response after funds disappear.
Crypto seizure and the new reality for criminals
The case also highlights an uncomfortable reality for illicit crypto users. Moving assets onto a blockchain does not necessarily make them invisible. Instead, transactions can leave a persistent digital trail that investigators may revisit years later.
That is precisely what makes this crypto seizure significant. The assets were connected to darknet activity dating back nearly a decade, yet specialist investigators were still able to trace their history.
Separately, the crypto sector is facing another wave of theft. In August 2026, blockchain-security researchers linked a fake Hyperliquid website promoted through Google advertising to infrastructure associated with Inferno Drainer after a victim lost about 550,000 USDC.
That incident is a separate case and should not be confused with the Avon and Somerset crypto seizure.
Ultimately, the latest crypto seizure sends a clear warning across the market: cryptocurrency may move at digital speed, but criminal transactions can leave evidence behind for years. For UK law enforcement, that trail is becoming an increasingly powerful weapon against money laundering, darknet commerce and organised financial crime.
