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.”
