London man jailed over ‘UKWhite’ dark web cocaine ring supplying 28kg across UK and abroad using crypto and anonymizing tech.
London, UK – A south London man has been sentenced to eight years in prison for his role in a sophisticated dark web cocaine distribution network operating under the alias “UKWhite.”
Helio Delfini, 43, of Rotherhithe Street in Southwark, was jailed on Friday April 17th 2026 after previously pleading guilty in March 2025 to conspiracy to supply cocaine.
Delfini worked alongside Lucas Costa and Bruno Teles, who were sentenced earlier in February 2026 to 14 years and 12 years respectively after being convicted of multiple drug offences, including conspiracy to supply cocaine and possession of Class C drugs with intent to supply.
The trio ran the “UKWhite” vendor account on the dark web, distributing cocaine across the UK and internationally. Investigators from the South West Regional Organised Crime Unit (SWROCU) uncovered thousands of transactions linked to the account, with more than 28 kilograms of high-purity cocaine sold over a 14-month period.
Authorities said the operation relied heavily on anonymising technologies and cryptocurrency payments to conceal identities and evade detection. Orders ranged from small half-gram purchases to bulk shipments exceeding 100 grams, all dispatched from addresses linked to the group in London.
Detective Inspector Ross Flay said the network demonstrated a high level of sophistication but was ultimately dismantled through extensive digital forensic analysis and international cooperation. Investigators were able to trace the online activity back to the suspects, identifying those behind the UKWhite marketplace presence.
The investigation began in 2020 and involved detailed analysis of digital evidence, ultimately exposing the scale of the operation and its reach beyond the UK.
Officials say the case highlights the continued use of the dark web and cryptocurrency in facilitating large-scale drug distribution, as well as law enforcement’s growing ability to track and shut down such
