In the early-morning hours of Feb. 19, a fleet of unmarked vehicles descended upon King Charles III's Sandringham Estate to arrest his younger brother Andrew Mountbatten-Windsor (formerly Prince Andrew) on suspicions of misconduct in public office. British authorities have been investigating Andrew, 66, over allegations that he shared confidential information with convicted sex offender Jeffrey Epstein while he worked as a trade envoy for the U.K. between 2001 and 2011.
