Police in Britain say the former prince, Andrew Mountbatten-Windsor, has been released under investigation following his arrest on suspicion of misconduct in public office. After being held for a day, he was photographed slouched in the back of a car leaving a police station in eastern England. Earlier his brother, King Charles, said the investigation would have the Royal Family's full support and co-operation. Police are looking into allegations that when he was a British trade envoy, he shared confidential documents with the late sex offender Jeffrey Epstein. Officers have searched his current and former homes at Sandringham and Windsor. Mr Mountbatten-Windsor has previously denied wrongdoing in relation to Epstein.
