Nine members of a gang which carried out a sophisticated cyber attack on a high street bank and stole £1.25 million by remote control gadgets have been jailed for a total of 24 years.

Another four are due to be sentenced in June, including 41-year-old Stephen Ohunta from Mafeking Road in Canning Town.

Ohunta faces sentence for conspiracy to commit fraud, theft and possessing criminal property when he appears at Wood Green Court on June 13.

He was part of an organised crime group across London which used a device known as a keyboard video mouse switch to get into Barclays and Santander accounts by remote control.

The gang also used bank and credit cards from a million intercepted or stolen letters to buy Rolex watches, designer jewellery, computers and iPads worth £1m.

“Their aim was to steal millions from banks and credit card companies,” said Det Chief Ins Jason Tunn, from the Met’s Cyber crime unit. “We have been able to bring this organised group to justice and are determined to make London a hostile place for cyber criminals.”

One cyber attack involved a gang member going into Barclays branch in Swiss Cottage and planting a remote device which let accomplices access the IT system from a nearby hotel. They used it to make 128 transfers totalling £1,250,000 to a network of “mule” accounts to launder the stolen cash. The bank managed to recover just £600,000.

Other cyber attacks were made on banks in Rotherhithe and Lewisham.

Detectives raided an address in Hounslow and arrested 10 men where they found computers that had got into the Santander system with staff log-in details, but had not got through its security.

The gang also managed to use genuine bank telephone numbers to fool customers into revealing personal account details and PIN numbers.

Nine were sentenced yesterday at Snaresbrook crown court in east London on various charges including fraud, conspiracy, possessing criminal devices and money laundering.
