Four men have been charged today in connection with the theft of £1.3 million from a Barclays Bank branch in Swiss Cottage.
The four men are 26 year old Michael Victor Harper, 34 year old Darius Bolder, 47 year old Tony Colston-Hayter and Lewis James Murphy, 29 years old - all from London.
They were charged with a variety of offences including conspiracy to steal and conspiracy to commit fraud by false representation.
They will be all appearing at Westminster Magistrates Court later on today.
The other four men arrested in connection with the theft have been bailed to a central London police station on dates in late November, pending further enquiries.
A gang of hi-tech hackers has targetted a bank in north London, getting away with £1.3 million. It's believed one of the gang posed as an IT engineer fixing a computer, to get access to the branch in Swiss Cottage.
It's the same method used unsuccessfully at a branch of Santander in East London. Banks say the hi-tech switch in tactics has become one of the biggest threats they face. Here's our Senior Correspondent, Ronke Phillips.
– Alex Grant, Barclays managing director of fraud prevention
Barclays has no higher priority than the protection and security of our customers against the actions of would-be fraudsters.
We have been working closely with the Metropolitan Police following a security breach at our Swiss Cottage branch in April 2013. We identified the fraud and acted swiftly to recover funds on the same day.
We can confirm that no customers suffered financial loss as a result of this action.
Police believe the gang that targeted Barclays had a "control room" in Seymour Place, Marylebone, central London.
The Barclays theft is being dealt with by the same investigation team that is dealing with the Santander attempted robbery.
A gang is alleged to have tried to use the KVM gadget to take control of all the computers at a branch of Santander in Surrey Quays shopping centre in south east London.
The attempt failed and the Spanish bank said they were unable to steal any money.
- A keyboard, video and mouse switch - known as a KVM - is a hardware device which is used legitimately in business to allow users to work remotely on their computer systems.
- It allows a user to control multiple computers from one keyboard, video monitor and mouse.
Barclays Banks reported a £1.3 million loss from its Swiss Cottage branch in April 2013 and an investigation was launched, Scotland Yard said.
Cash, jewellery, drugs, thousands of credit cards and personal data have been seized in searches at addresses in Westminster, Newham, Camden, Brent and Essex.
Detectives described one of the addresses in central London as the fraudsters' control centre.

Those responsible for this offence are significantplayers within a sophisticated and determined Organised Criminal Network, whoused considerable technical abilities and traditional criminal know-how toinfiltrate and exploit secure banking systems.
A KVM device, which allows users to work remotely on a system, and 3G router were found connected to a computer at the Swiss Cottage branch in north London.
A male purporting to be an IT engineer allegedly accessed the branch the day before the theft and attached the KVM device, Scotland Yard said.
This allegedly allowed a group to remotely transfer money to a predetermined bank account.
The men, aged between 24 and 47, were arrested in connection with an allegation of conspiracy to steal from Barclays Bank and conspiracy to defraud UK banks, Scotland Yard said.
They remain in custody at a London police station.
