Andrew Mountbatten-Windsor was arrested by Thames Valley Police and remains in custody. Officers have also been carrying out searches at properties in Berkshire and Norfolk after formally launching an investigation.
A 66th Birthday Marked by Investigation
The 66-year-old was detained on suspicion of misconduct in public office following what police described as a “thorough assessment” of the allegation. The case is now active.
Earlier that day, unmarked police vehicles were seen at Sandringham in Norfolk, where Andrew has been living since leaving Royal Lodge in Windsor Great Park. Searches are also underway in Berkshire.
In a statement, Thames Valley Police declined to name him directly, confirming only that a man in his sixties had been arrested.
The force said, “We will not be naming the arrested man, as per national guidance. Please also remember that this case is now active, so care should be taken with any publication to avoid being in contempt of court.”
Assistant Chief Constable Oliver Wright added, “Following a thorough assessment, we have now opened an investigation into this allegation of misconduct in public office. It is important that we protect the integrity and objectivity of our investigation as we work with our partners to investigate this alleged offence.”
He acknowledged the considerable public interest and said updates would be provided when appropriate.

A Royal First in Modern History
Although Andrew has previously faced serious allegations connected to his association with convicted sex offender Jeffrey Epstein — claims he has consistently and firmly denied — this is the first time he has been arrested.
He is now the first senior royal in modern times to be taken into custody.
Police had earlier confirmed they were reviewing allegations that Epstein trafficked a woman to the UK for a sexual encounter involving Andrew, as well as claims that he may have shared sensitive information with Epstein while serving as the UK’s trade envoy.
His detention follows a separate Metropolitan Police review into allegations concerning former close protection officers assigned to him. That inquiry stated it had “not identified any wrongdoing,” though “initial enquiries into these specific allegations have begun so we can establish the facts.”
