Investigators complete seven-hour Cambridge Analytica HQ search

Officials raid firm’s London offices amid allegations it may have illegally acquired data

Investigators from Britain’s data watchdog have spent nearly seven hours searching the London offices of Cambridge Analytica.

Eighteen enforcement officers entered the Cambridge Analytica headquarters in London’s West End on Friday night to search the premises after the Information Commissioner’s Office (ICO) was granted a warrant to examine its records.

The officials concluded the search at about 3am on Saturday.

“We will now need to assess and consider the evidence before deciding the next steps and coming to any conclusions,” an ICO spokesperson said in a statement.

A judge had issued the warrant on Friday evening, four days after the information commissioner, Elizabeth Denham, first announced plans to raid the offices.

Denham has been seeking access to records held by the London-based data analytics company, which faces allegations it may have illegally acquired the information of millions of Facebook users and used it to profile and target voters during political campaigns.

Mr Justice Leonard granted the warrant after a five-hour hearing at the Royal Courts of Justice, adjourned from Wednesday.

A spokesperson for the ICO said: “This is just one part of a larger investigation into the use of personal data and analytics for political purposes.”

The focus of the data watchdog’s investigation includes the acquisition and use of Facebook data by Cambridge Analytica, its parent company, SCL, and Dr Aleksandr Kogan, the academic who developed the app used to gather the data.

The growing scandal stems from claims over the harvesting of personal data and whether it was used to affect the outcome of Donald Trump’s US presidential campaign and the EU referendum.

Less than an hour after the warrant was granted a group of 18 people, some wearing ICO enforcement jackets, entered the building from New Oxford Street, led by a woman holding a piece of paper that appeared to be a warrant.

The enforcement officers were seen on the second floor – where Cambridge Analytica is thought to have its offices.

It is understood they were searching for correspondence and communications between SCL and Kogan’s company Global Science Research (GSR), as well as data obtained from Facebook via Kogan.

News of the raid came as the acting CEO of Cambridge Analytica, Dr Alexander Tayler, who was appointed after the suspension of Alexander Nix, issued an apology about the way some data had been collected by an affiliate company.

“I am sorry that, in 2014, SCL Elections [an affiliate of Cambridge Analytica] licensed Facebook data from a research company [GSR] that had not received consent from respondents,” he said. “The company believed the data had been obtained in line with Facebook’s terms of service and data protection laws.

“We are now undertaking an independent, third-party audit to verify that we do not hold any GSR data.”Tayler went on to deny that a former employee who provided documents and information about Cambridge Analytica to the Observer was a whistleblower.

He said: “The source of allegations against the company is not a whistleblower or a founder of the company. Christopher Wylie was a part-time contractor who left in July 2014 and has no direct knowledge of our work or practices since that date.

“He was at the company for less than a year, after which he was made the subject of restraining undertakings to prevent his misuse of the company’s intellectual property while attempting to set up his own rival firm.”

Meanwhile, pressure is mounting on the Facebook founder Mark Zuckerberg, who has been called to give evidence to MPs.

Cambridge Analytica, SCL, Kogan and Facebook deny any wrongdoing.

Earlier in the week, the culture secretary, Matt Hancock, hinted that the government would consider further strengthening the information commissioner’s powers to investigate the misuse of personal data amid criticism that it had taken so long to get a search warrant.

Following Friday’s hearing, Leonard said he would outline the reasons for his decision on Tuesday.
