This is the moment a computer hacker dubbed ‘Courvoisier’ was arrested for carrying out cyber attacks on some of Britain’s top companies and selling customers’ data on the dark web.

Police seized £500,000 in Bitcoin from Grant West after discovering he had obtained the personal data of millions of people and more than 60,000 credit details.

With the help of his girlfriend Rachael Bookes, he carried out cyber attacks on companies including Sainsbury’s, Asda, Uber, Argos and bookmakers Ladbrokes and Coral.

In 2015, he managed to obtain the details of 165,000 customers from the takeaway app Just Eat, costing the company £200,000 to sort out.  

West drove around in a £40,000 Audi A5 coupé and blew some of his Bitcoin fortune on a gambling trip to Las Vegas.

West, who operated from a caravan park in Sheerness in Kent, was arrested by officers from Scotland Yard’s Cyber Crime Unit while he was travelling first class on a train.

CCTV caught the moment officers stormed the carriage and handcuffed him, taking a red laptop from an overhead shelf.

The case is the first time the Met Police have seized criminal property in the form of cyber-currency, as a huge battle with hackers and cyber criminals is played out behind the scenes.

West, 26, attacked the websites of more than 100 companies worldwide. 

He then sold information on the dark web, where computer users can operate untraced, and splashed out on holidays and shopping trips.

‘Phishing’ scam emails to customers, by fraudsters designed to look like they had come from the companies, asking them to confirm their financial details.

He made at least 47,000 sales of data through the dark web, police said following a two-year investigation.

Officers found approximately 78million individual usernames and passwords and 63,000 credit and debit card details stored on an SD card in his caravan.

West admitted two counts of conspiracy to defraud, one charge of computer hacking, four charges relating to the possession and supply of cannabis, two counts of possessing criminal property and one count of money laundering Bitcoins.

His girlfriend Brookes, of Denbigh, north Wales, whose computer West used in at least one of the attacks, admitted unauthorised use of computer material.

She cried today as she was released with a two year community order and curfew at Southwark Crown Court today. West will be sentenced later this month.

Detective Chief Superintendent Mick Gallagher said of the investigation: ”It’s the first of its kind, not as much as you see a large quantity of bitcoin, but because of the combination of technology and the technological response to it.’

Case officer DC Helen Foster said the fraud came to light after a referral from Action Fraud who said customers from Just Eat had complained about a ‘phishing email’.

The emails, sent out to customers, purported to be a survey that would give the customer a £10 voucher to use on the site.

But unsuspecting punters were handing over more of their personal details which West then flogged on the Dark Web.

Police believe he hacked around 500 companies – including Sainsbury’s, Nectar, Groupon,, Ladbrokes, Coral Betting, Uber, Vitality, RS Feva Class Association 2017, Asda, the British Cardiovascular Society, Mighty Deals Limited, Truly Experiences Ltd, T Mobile, M R Porter, the Finnish Bitcoin exchange, and Argos.
