Earlier, the Information Commission Office Twitter account posted: "ICO granted warrant: We're pleased with the decision of the judge and we plan to execute the warrant shortly".
The lawsuit, filed by Matthew Lodowski, also targets Cambridge Analytica for its role in mining the private data. A whistleblower detailed how users' data was illegally acquired and used to build profiles of American voters ahead of the 2016 USA presidential election.
