A Chinese national has been sentenced for orchestrating a £5 billion money laundering operation involving the world’s largest confirmed cryptocurrency seizure, following a landmark, seven-year Metropolitan Police investigation.
Multi-Year International Fraud and Money Laundering Uncovered
Zhimin Qian, 47, of no fixed address, received an 11-year and eight-month prison sentence for her role in one of the most significant economic crimes in UK history. Between 2014 and 2017, Qian engineered a vast fraud scheme in China, deceiving over 128,000 victims and accumulating illicit funds on an unprecedented scale.
To obscure the money’s origins, Qian converted substantial portions of the stolen proceeds into cash, high-value jewellery, and Bitcoin. Utilizing an assumed identity, she fled to the UK, hoping to exploit international financial systems to launder the criminal proceeds.
Her elaborate efforts culminated in the transfer and possession of criminal property, primarily cryptocurrency, in contravention of the Proceeds of Crime Act (2002).
Working with UK intelligence received in 2018 about attempts to realize these criminal assets in London, the Met’s Economic Crime team launched a complex operation.
This culminated in the recovery of over 61,000 Bitcoin from Qian, valued at around £5 billion, representing the largest confirmed crypto seizure worldwide. Additional civil recovery proceedings to secure these digital assets are ongoing, aiming to prevent the defendants from profiting further.
Technical Complexity and Interagency Collaboration
Seng Hok Ling, 47, of Matlock, Derbyshire, was also convicted and sentenced to four years and 11 months for transferring criminal property.
The investigation required coordinated efforts from specialist teams within the Metropolitan Police, the Crown Prosecution Service (CPS), the National Crime Agency, and international law enforcement partners, particularly from China.
The technical investigation highlighted advanced techniques for cryptocurrency tracing. Blockchain analysis enabled officers to follow digital money trails, uncovering how criminals leverage virtual assets to mask illicit activity while ensuring immutable transaction records.
This established strong evidence, prompting guilty pleas and ultimately the sentences imposed on Qian and Ling.
Crypto Crime Prevention and Victim Impact
Law enforcement leaders and public officials, including Mayor Sadiq Khan and Security Minister Dan Jarvis, praised the operation and emphasized the growing threat of cryptocurrency-enabled crime.
They warned of the dangers associated with high-risk, unregulated investment opportunities and advised the public to exercise increased caution. The CPS is committed to pursuing all avenues to bring about justice for the victims.
Authorities urge anyone affected by similar frauds to follow crime-prevention guidance: verify investment credentials using official sources such as the FCA, approach all offers with skepticism, particularly those promising high returns with minimal risk, and promptly report any suspicious activity to Action Fraud.
For further information and support, victims can consult crime prevention booklets and use online scam-checking tools.
This landmark case sets a global benchmark for technical and legal responses to cryptocurrency abuse in organized crime, illustrating the power of cross-border investigations and advanced forensic methods to trace and recover digital wealth.
