Through thorough digital forensic work, law enforcement tracked each step of every transaction so, they identified the three individual co-defendants.
A man from South London will spend the next eight years in prison for running a sophisticated cocaine operation on the dark web. Helio Delfini, 43, of Rotherhithe Street in Southwark – received his sentence at Bristol Crown Court on Friday, April 17. He had pleaded guilty to conspiracy to supply cocaine back in March of last year.
Alongside other men, Lucas Costa and Bruno Teles, Delfini operated an online drug distribution business under the vendor name UKWhite, using dark web marketplaces to facilitate their sales. In February, the judge sentenced Costa to 14 years and Teles to 12 years for various drug offenses.
Police Spent Years Tracking the Online Drug Ring
The South West Regional Organized Crime Unit, the SWROCU, started investigating the network back in 2020. The team uncovered thousands of transactions linked to the UKWhite account – their work showed that the trio moved more than 28 kilograms of high-purity cocaine over just 14 months.
Detective Inspector Ross Flay of SWROCU explained that Delfini and his partners relied on anonymizing technology and cryptocurrency payments to hide their tracks from their home base in London.
However, the detective added that painstaking digital forensic work, combined with support from international partners, allowed the police to identify the people behind UKWhite and remove this vendor from the dark web.
The NCA has previously carried out large-scale operations targeting criminal networks that used encrypted communications. The NCA’s operation, called Operation Venetic, was the UK’s response to the takedown of the EncroChat platform and has been successful in dismantling many criminal organizations that thought they could operate in secret.
Customers Bought Cocaine in Tiny and Bulk Amounts
The investigation revealed that UKWhite sold cocaine to buyers in quantities ranging from half-gram deals all the way up to bulk orders of 100 grams or more. The gang shipped the drugs from their London addresses to customers across the United Kingdom and to international buyers as well.
Continuous pressure is being placed upon the dark web’s illegal drug trade by law enforcement from all around the world. Recently in New Zealand, police executed 16 search warrants in Auckland and Hamilton related to Operation Solana, targeting a syndicate importing drugs via dark web markets from the United Kingdom, Europe and the USA.
This global pressure also extends to other dark web markets, UK Cyber Police recently dismantled ‘SocialPharma’, a fake pharmacy that made millions selling counterfeit and unlicensed medications, showing that authorities are targeting all forms of dark web commerce that endanger public health.
Detective Inspector Flay stated that the successful crackdown on the UKWhite network sends a clear message. The detective said that the dark web drug trade cannot hide from relentless police work. He added that authorities will continue pursuing dealers who believe technology can protect them from prosecution.
The Digital Forensics Hold the Key to Exposing the Drug Dealers
The experts spent numerous months following the online activity of the three men. The digital forensics consisted of examining thousands of transactions and following complicated cryptocurrency trails. They partnered with law enforcement agencies globally to help track the extent of the network outside of the UK.
The South West Regional Organized Crime Unit announced on April 17 that the outcomes of the cases against the three members of the UKWhite operation, the sentencing of Delfini, were resolved and concluded. A public statement the police unit posted on April 20 outlined the details of the investigation and the outcomes of the sentencing.
The number of successfully prosecuted cases against dark web drug suppliers continues to grow. One of the pieces of evidence is the sentencing of another Bridgend man in February 2026, who after his arrest, admitted to purchasing drugs from the dark web for the purpose of self-medicating. The authorities later determined that he was buying the drugs to sell to others.
The SWROCU is continuing its partnership with law enforcement agencies worldwide to identify and prosecute other dark web vendors. Detective Inspector Flay from the SWROCU has stated that the unit will continue with its commitment to get rid of illegal online drug suppliers and take them to justice.
