Andrew Mountbatten-Windsor has been arrested - on his 66th birthday

According to the BBC, a statement from Thames Valley police reads: "As part of the investigation, we have today (19/2) arrested a man in his sixties from Norfolk on suspicion of misconduct in public office and are carrying out searches at addresses in Berkshire and Norfolk.

"The man remains in police custody at this time.

"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 said: "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.

"We understand the significant public interest in this case, and we will provide updates at the appropriate time."

Andrew's arrest comes just days after King Charles admitted he was "profoundly concerned" by allegations relating to his brother's "conduct".

Earlier this month, Buckingham Palace confirmed it is prepared to support the police as they consider allegations against Andrew, who is the younger brother of the King.

A Palace spokesperson said: "The King has made clear, in words and through unprecedented actions, his profound concern at allegations which continue to come to light in respect of Mr Mountbatten-Windsor's conduct.

"While the specific claims in question are for Mr Mountbatten-Windsor to address, if we are approached by Thames Valley Police we stand ready to support them as you would expect.

"As was previously stated, Their Majesties' thoughts and sympathies have been, and remain with, the victims of any and all forms of abuse."

It was recently reported that Thames Valley Police were assessing whether there are grounds to investigate a complaint by Republic, a high-profile anti-monarchy group, which reported Mountbatten-Windsor for suspected misconduct in public office and breach of official secrets.

The Prince and Princess of Wales previously confessed to being "deeply concerned" by the ongoing revelations from the Epstein files.

The royal couple addressed the controversy before embarking on a trip to Saudi Arabia.

A spokesperson for William and his wife Catherine told media: "I can confirm The Prince and Princess have been deeply concerned by the continuing revelations. Their thoughts remain focused on the victims."

Andrew has previously been accused of sharing sensitive information with Jeffrey Epstein, the late sex offender, from his role as a UK trade envoy.

He has denied any wrongdoing.

Andrew was stripped of his title and royal privileges by King Charles last October, and is now living on the Sandringham Estate.
