The Metropolitan Police's seven-year investigation into a record-setting fraudster has ended after she was sentenced to 11 years and eight months in prison on Tuesday.

It follows Zhimin Qian [1]pleading guilty to two charges in September, both related to criminal property, namely cryptocurrency. She faced one charge for possessing and another for transferring criminal property, both under the Proceeds of Crime Act 2002.

Qian was on the run since 2017 after carrying out a large-scale fraud in China between 2014 and 2017, which affected more than 128,000 people.

She established Lantian Gerui, a company in China that ostensibly developed technology and mined Bitcoin, attracting many investors whose funds were later misappropriated.

The 47-year-old, of no fixed address, fled China in 2017 to the UK, traveling under false documents and an assumed identity, after converting the stolen funds into cash, jewellery, and [5]Bitcoin .

She rented a mansion in the affluent London borough of Hampstead, which police raided a year later after receiving intelligence of an attempted realization of criminal assets in London.

[6]

The raid led to the seizure of her incredible stash of more than 61,000 Bitcoin, which at today's value is worth £4.8 billion ($6.3 billion) and is thought to be the single largest confirmed cryptocurrency seizure in history.

Qian tried to launder the Bitcoin by purchasing property in London and overseas, using other people in a bid to avoid investigations into the source of her wealth.

These attempts led to the sentencing of a former assistant, Jian Wen, 44, to six years and eight months in prison in 2024 for helping Qian purchase properties in Dubai back in 2019.

Will Lyne, head of the Met's Economic and Cybercrime Command, said: "This outcome is the result of seven years of dedicated investigation by specialist teams from across the Met.

"There is no doubt this is one of the largest and most complex economic crime investigations we have ever undertaken, and today's sentence would not have been possible without working closely with our partners from the Crown Prosecution Service, National Crime Agency, and Chinese law enforcement.

"Organized crime groups are using cryptocurrency to move, hide, and invest the profits of serious crime – but every crypto transaction leaves a trace, and the Met works meticulously with partners to follow that digital trail, identify assets, and bring offenders to justice.

"Our message is clear – criminal assets are not safe in the UK. The Met remains committed to protecting the public and this outcome shows the lengths we will go to secure justice for victims."

Another associate of Qian's, 47-year-old Seng Hok Ling, was sentenced alongside the master fraudster at Southwark Crown Court yesterday to four years and 11 months for transferring criminal property, namely cryptocurrency, under the Proceeds of Crime Act 2002.

Lead prosecutor Neil Colville said: "The imprisoning/sentencing of Zhimin Qian and Seng Hok Ling marks the culmination of many years of complex and detailed work by both the Metropolitan Police and the Crown Prosecution Service. The fact that the defendants pleaded guilty are testament to the thoroughness of the investigation and prosecution.

"The CPS will now work to ensure, through criminal confiscation and civil proceedings, that the criminal assets remain beyond the fraudsters' reach to firstly freeze and then look to seize the very large quantity of cryptocurrency and other assets, currently worth around £4.8 billion, used by Zhimin Qian to fund her extravagant lifestyle."

NCA's crypto campaign

While not linked to the news this week, the National Crime Agency's (NCA) latest campaign targeting males under 45 coincides with Qian's sentencing.

It said the target demographic is the most commonly associated with cryptocurrency fraud, which "costs the public millions every year."

According to Action Fraud, the UK's reporting center for fraud and cybercrime, it received more than 17,000 reports of crypto investment fraud in 2024, often from men aged between 25 and 44.

"Crypto Dream Scam Nightmare" is the strapline of the campaign, which aims to highlight the risks of investing in [12]dodgy crypto schemes , whose operators routinely make off with investors' cash.

A common method utilized by these scammers is to offer access to a fake investment platform, which appears to show investors' funds growing in time.

They also often claim that money can be withdrawn at any time, but the funds are stolen at the point they are first invested.

One individual who spoke for the campaign said he was led to believe his £28,000 ($36,726) investment grew to £400,000 ($524,664) in six months, but was in fact stolen.

Nick Sharp, deputy director of fraud at the National Economic Crime Centre (NECC) in the NCA, [13]said : "Crypto investment fraud is one of the fastest growing types of fraud in the UK, experienced by those who believe their 'investment' will vastly grow their money. The knowledge that their money has, in truth, been stolen and they will never see any returns is a financial and emotional loss. Lives are destroyed and people can sometimes never be made whole after falling victim to this crime.

"That is why the NCA is actively targeting and disrupting the criminal networks behind crypto investment fraud through investigations and intelligence sharing with international partners. However, prevention remains equally as important as disruptions. ®
