Thames Valley Police, who made the arrest, said it was on "suspicion of misconduct in public office", a so-called "common law offense," that is a crime established by a combination of legal precedent and custom, not by a formal act of parliament. While the nature of the alleged offence has not yet been made clear, Mountbatten-Windsor, known as Prince Andrew until being stripped of his titles last year, has been heavily linked to disgraced and deceased sex offender Jeffrey Epstein.
