A phishing scammer who obtained thousands of bank details from Lloyds customers has been jailed after police discovered indecent images of children on his computer.

In May 2013 Lewys Martin, from Deal, contacted Lloyds Bank, threatening to reveal thousands of customers' details, illegally obtained using phishing software.

The 22-year-old blackmailer demanded £207,000 from the bank to be paid in Bitcoins, an untraceable digital currency.

Martin included samples of the stolen details to prove he was genuine, but the bank contacted the police.

The Metropolitan Police Cyber Crime Unit launched an investigation and traced the blackmail threat to Martin.

Detectives seized his computer and phone and found stolen bank account data - including 740,000 email addresses - as well as three programs designed for phishing.

But that was not all they discovered - Martin also had a number of indecent images of children stored on his system.

Martin pleaded guilty to blackmail, possession of articles for use in fraud, and possession of indecent images of children.

He was jailed for 27 months for the fraud and blackmail and 23 months for possessing indecent images of children - a total of four years and two months in prison.

He was also given a five-year Sexual Offences Prevention Order at Southwark Crown Court.
