Investigation into King Charles' brother Andrew will take a long time

investigation into Andrew Mountbatten-Windsor will be long and complex, senior officers said on Friday, after his arrest earlier this year on suspicion of misconduct in public office, an offence that can include sexual impropriety. King Charles' younger brother was interviewed under caution for hours by detectives after he was arrested at his home in Norfolk in February following the release of millions of documents by the U.S. Department of Justice relating to the late U.S. sex offender Jeffrey Epstein. The arrest of the senior royal, eighth in line to the throne, was unprecedented in modern times. A Reuters photo of the ashen-faced former prince leaving the police station made front pages around the world. Mountbatten-Windsor, 66, the second son of the late Queen Elizabeth, has always denied any wrongdoing in relation to Epstein, and said he regrets their friendship. He has made no public statement since his arrest.
