The U.K.'s data protection watchdog ordered Facebook to stand down Monday when auditors hired by the social network visited the offices of a political analytics company accused of wrongly harvesting the data of millions of its users.
The Information Commissioner's Office (ICO) told the tech giant, which was planning to investigate Cambridge Analytica's servers and systems, to withdraw from the latter's London premises. The ICO said it would seek to gain its own warrant to access the company's computers and servers.
Yeah, I'm pretty sure the UK government has more authority than some workers from Facebook...
