A high-tech fraudster, who used an electronic SMS blaster stored in a large suitcase to spam rush hour commuters with fraudulent text messages, has been jailed.
Kong Ji Chen, 31, received twenty-four weeks imprisonment for bombarding tube train passengers with spam text messages as they travelled on the busy Victoria Line.
Inner London Crown Court heard on Tuesday, July 1 at approximately 5.30pm a passenger received a spam text message.
The text claimed to be from Parcel Mail and invited the reader to click on a link to update their details in order to receive a package.
Users who did so would then be asked to enter in their personal details.
The passenger was familiar with SMS blasters and grew suspicious of Chen when he noticed him loitering with a large suitcase, not getting on any trains or moving on from the platform.
Local officers were alerted and arrived at Victoria Underground station, where Chen was found sitting on a bench next to a large green suitcase.
Chen claimed he was waiting for a friend, and claimed the suitcase had been given to him earlier in the day by another man.
Officers searched the suitcase and upon opening it saw a portable battery attached to an electrical unit with a green flashing light and a black antenna.
Chen was then immediately arrested and taken into custody.
A technical security adviser reported that there were 165 reports to mobile phone carriers of the same spam text message coming from the same number between 2.38pm and 10.37pm on July 1.
Investigating officer DC Adrienne Curzon said: "I'm very pleased with the result in this case. Chen targeted potentially thousands of commuters, attempting to harvest their data.
“The conviction was achieved thanks to the close work our officers undertook with mobile network operators including BT, Virgin Media O2, and Vodafone as well as the National Cyber Security Centre and Ofcom.
"Thanks to the vigilance of one member of the public, our officers were able to act and prevent more people from being targeted and becoming victims of Chen's fraudulent endeavour.”
