Another Chinese text fraudster behind a fake HMRC message that aimed to dupe unsuspecting recipients, has been convicted.
Di Li, 43, of Wentworth Park, Finchley employed an accomplice to drive around north London with an 'SMS Blaster' device, which delivered fake messages from the UK's taxman.
He was tracked down after officers from the City of London Police's Dedicated Card and Payment Crime Unit (DCPCU) investigated the accomplice.
Li is now starting a four-year prison sentence after an Inner London Crown Court jury convicted him of conspiracy to defraud and providing articles for use in fraud.
The 'SMS Blaster' is a high-level piece of equipment, which acts as an illegitimate mobile phone mast.
It forces nearby mobile devices to connect to it, diverting them away from their legitimate network providers.
By doing so, criminals can bypass safeguards designed to block malicious sender names and harmful links, enabling them to deliver fraudulent messages directly to victims.
Officers near Li's accomplice received the fake HMRC text messages and arrested him.
Detective Inspector Andrew Little, from the DCPCU, said:
“This case highlights the role of those working behind the scenes to enable fraud at scale.
“While individuals may be deployed on the ground, it is organisers who facilitate and sustain this criminal activity.
“SMS blaster devices represent a significant threat, allowing criminals to bypass protections and target members of the public with convincing scam messages.
“We urge the public to remain vigilant. If you receive a suspicious text message, do not engage with it. Instead, forward it to 7726, a free reporting service, and block the number.
These reports help us and our partners to disrupt fraud and protect others.”
The investigation found that Li facilitated his fellow-Chinese accomplice's involvement by arranging access to the SMS blaster device, assisting with obtaining a vehicle, and supporting his day-to-day living costs.
The accomplice, who had accrued significant gambling debts after arriving in the UK as a student, was instructed that he could repay what he owed by driving routes and operating the equipment as directed.
The device was installed in the vehicle, and the accomplice was provided with routes and timings to follow while deploying the equipment.
This “testing” phase was coordinated remotely by Li and others involved in the wider network.
On August 20, 2025 officers executed a warrant at Li’s home address, where digital evidence was recovered showing communications between Li and his accomplice relating to the deployment of the SMS blaster.
At trial, Li claimed that the device was intended for “advertising” purposes and described himself as a middleman acting on behalf of an individual based in China.
