Coinbase used blockchain forensics to help UK law enforcement secure five criminal convictions tied to a violent kidnapping. Its Global Intelligence team traced stolen funds onchain in real time as the attack unfolded.
The case began last July, when a 36-year-old Hertfordshire man met four strangers at a Shoreditch bar in east London. They later forced him home and coerced him into opening several accounts, including Coinbase.
Coinbase Blockchain Forensics Traced Stolen Funds
When the attackers tried to move funds off the platform, Coinbase’s internal systems reportedly flagged the customer as under duress.
The exchange contacted UK police while the crime was still in progress, then mapped the flow of stolen assets.
Investigators traced £1,900 ($2,500) in crypto plus additional fiat across multiple wallets. They linked one address to a suspect who held a Coinbase account. Data and expert testimony were presented to St Albans Crown Court.
Four defendants were convicted of conspiracy to rob, kidnapping, and false imprisonment. A fifth was convicted of money laundering. The Hertfordshire Major Crime Unit led the local investigation.
“Our investigations team worked with UK law enforcement to successfully track and convict five individuals involved in crypto-related kidnapping. Blockchains allowed us to spot and trace their actions in real time as it was happening,” said Paul Grewal, Coinbase Chief Legal Officer.

The verdict lands as physical crypto kidnappings and wrench attacks continue to rise.
CertiK documented 34 verified physical attacks on token holders between January and April 2026. London has emerged as a hotspot for muggings targeting wallet apps.
The convictions add to a growing record of blockchain forensics work, tying public ledgers to criminal prosecutions. Exchanges are leaning on this defense as crypto-related violence climbs.
