UK police are conducting their fourth day of investigation at Andrew Mountbatten-Windsor's former residence following his arrest for misconduct in public office. The probe involves 10 police forces examining multiple allegations connected to his friendship with Jeffrey Epstein, and he faces potential removal from his current position as eighth in the royal line of succession. Andrew was arrested after six unmarked police cars arrived at the King's Sandringham estate, interviewed for over 11 hours, and has been released under investigation.
