A Sri Lankan software engineer has been sentenced to four years in jail for his part in a 'chip and PIN' scam that stole £725,000 from petrol station customers in the south of England.
Theogones De Montford made modified circuits for chip and PIN machines at Shell and Texaco petrol stations across Cambridgeshire, Leicestershire and Kent.
De Montford secretly installed modified circuits into the machines through a hole drilled into the back of the reader. The devices then sent the card details of motorists using the petrol stations to De Montford via Bluetooth.
The card details collected by de Montford were then sold to fraudsters for as much as £1,000 per PIN number.
Other members of De Montford's gang, Rajakumar Thevathasan, Rashid Hassan and Usman Mahmood have each received jail terms of three and a half years.
The prosecutor, Adam Budworth, said: "He [De Montford] was perhaps one of the most prolific chip and PIN fraudsters in the UK. Since his arrest there has been a significant reduction in the number of chip and PIN frauds in the UK."
Budworth went on to state that the cases highlighted in court were "only the tip of the iceberg", and that De Montford and the gang may have stolen millions during the nine-month period in which they were active.
