DATA WATCHDOG RAIDS CAMBRIDGE ANALYTICA OFFICE

Officers from Britain’s information regulator raided the London offices of data firm Cambridge Analytica Friday after being granted a warrant as part of a probe into alleged misuse of personal information. A High Court judge granted the warrant Friday. Soon afterward, 18 people, some from the Information Commissioner’s Office, entered the company’s central London offices. The commissioner is investigating whether the firm improperly used data from some 50 million Facebook users to target voters with political messages.
