The statement added: "This is one part of a larger investigation by the ICO into the use of personal data and analytics by political campaigns, parties, social media companies and other commercial actors".
British regulators finished searching the offices of Cambridge Analytica, the firm at the center of a Facebook data scandal, before dawn today and said they would examine the evidence before considering "next steps".
A group of 18 people, some wearing ICO enforcement jackets, had arrived at the building less than an hour after a High Court judge granted the search warrant sought by the Information Commissioner's Office (ICO).
Elizabeth Denham, the Information Commissioner, has requested urgent access to the records of Cambridge Analytica, a company accused of harvesting the records of 50 million Facebook users.
A full explanation of the legal ruling by Judge Anthony James Leonard will be issued on Tuesday, according to the court.
It stems from claims over the harvesting of personal data - and whether it was used during Donald Trump's United States presidential campaign or the Brexit referendum.
In a separate development, Brittany Kaiser, Cambridge Analytica's former business development director, has told the Guardian the firm carried out data analysis for Leave.EU, the rival Brexit campaign to Vote Leave that was fronted by Nigel Farage.

It includes zero tariffs on goods, reciprocal access to fishing waters and cooperation in defence and foreign affairs. The British fishing industry want the United Kingdom to have sole control of its waters after the transition.
Last month, Cambridge Analytica Chief Executive Alexander Nix denied to a parliamentary committee the company worked for Leave. "In my opinion I felt like we should say, 'this is exactly what we did'".
British lawmakers have requested Zuckerberg and Nix appear before the Parliament to answer questions about the alleged data misuse.
The data watchdog's investigation includes the acquisition and use of Facebook data by CA, its parent company SCL and academic Dr Aleksandr Kogan, who developed the app used to gather data.
"The company (CA) believed that the data had been obtained in line with Facebook's terms of service and data protection laws", Tayler said.
"I'm being basically used as a scapegoat by both Facebook and Cambridge Analytica", he said in interviews Wednesday.
Cambridge Analytica and Facebook have denied committing any crimes.
However, Cambridge University announced Friday it was "undertaking a wide-ranging review" of the episode and had written to Facebook "to request all relevant evidence in their possession".
