Investigators from Britain's data watchdog searched the London offices of Cambridge Analytica, the data analytics firm at the center of a storm over allegations it improperly harvested Facebook data to target U.S. voters.

About 20 officials, wearing black jackets with "ICO Enforcement" on them, arrived at the firm's central London offices on Friday evening soon after a High Court judge granted a search warrant sought by the Information Commissioner's Office (ICO).
