Andrew Mountbatten-Windsor has been released from police custody after being taken into custody on Thursday over allegations of misconduct in public office.

The 66-year-old, who celebrated his birthday on the same day, was apprehended during a morning raid at his residence, Wood Farm, located on the Sandringham estate.

Thames Valley Police reported the arrest occurred shortly after 10 a.m., granting the authorities a 24-hour window to detain him without charges from the time he reached the police station.

The conditions of his release remain unclear, as it is unknown whether Andrew has been let go under investigation or on bail, with the latter often carrying specific stipulations.

The arrest is reportedly linked to accusations that the former Duke of York shared confidential information with Jeffrey Epstein, a convicted sex offender, during his tenure as a trade envoy for the British government.

In a surprising turn, it has been revealed that King Charles III, Andrew’s brother, was not informed ahead of the arrest. However, the Daily Mail disclosed that Home Secretary Shabana Mahmood’s team was notified by a senior officer earlier in the morning.

The monarch said in an unprecedented statement that ‘the law must take its course’ after expressing his ‘deepest concern’ after his younger brother was held on suspicion of misconduct in public office.

Charles said: ‘I have learned with the deepest concern the news about Andrew Mountbatten-Windsor and suspicion of misconduct in public office.

‘What now follows is the full, fair and proper process by which this issue is investigated in the appropriate manner and by the appropriate authorities. In this, as I have said before, they have our full and wholehearted support and co-operation.

‘Let me state clearly: the law must take its course.

‘As this process continues, it would not be right for me to comment further on this matter. Meanwhile, my family and I will continue in our duty and service to you all’.

The Prince and Princess of Wales are said to support the statement.

The Daily Mail was the first to reveal plain-clothes police, carried in six unmarked vehicles, had arrived at Wood Farm, where Andrew now lives, around 8am this morning. 

Onlookers said the group of eight people were in plain clothes ‘but appeared to be police officers’. One man appeared to be carrying a police-issue laptop.

A convoy including at least two royal Land Rovers linked to Andrew was photographed leaving the estate less than an hour later. His arrest was confirmed at 10.08am. 

A fine art transportation company van and multiple police vehicles were also seen at Andrew Mountbatten-Windsor’s former Berkshire residence, a few miles south of Windsor Castle.

At around 4pm, a dark blue Gander and White van was seen leaving the outer gates of the Windsor Great Park, which surrounds the Royal Lodge estate.

Gander and White describes itself as ‘one of the world’s leading fine art logistics companies, providing art storage, transport, installation and customs services’.

Two large police vans with tinted windows, each carrying several uniformed officers, were also seen leaving the property.

A Thames Valley spokesperson said: ‘We have today arrested a man in his sixties from Norfolk on suspicion of misconduct in public office’.

The force said its officers are searching an address in Norfolk – believed to be Wood Farm where Andrew is exiled – and an address in Berkshire, likely to be Royal Lodge in Windsor, where he lived for more than 20 years until this month.

Norfolk Police said it is ‘supporting’ the Thames Valley investigation but did not initally say if one of its stations was being used by detectives to interview Andrew.

Thames Valley 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.’

For the past ten days detectives have been probing Andrew’s conduct as a trade envoy for the UK, after emails in the Epstein Files suggested he shared confidential information with his paedophile friend, including reports of his official visits and potential investment opportunities.

Emails released by the US Department of Justice appeared to show the former duke sharing reports of official visits to Hong Kong, Vietnam and Singapore.

One email, dated November 2010, appeared to be forwarded by Andrew five minutes after being sent by his then-special adviser Amir Patel.

Another, on Christmas Eve 2010, appeared to send Epstein a confidential brief on investment opportunities in the reconstruction of Helmand Province, Afghanistan.

While in custody, experts told how Andrew would be given no special treatment and would undergo the usual police formalities including fingerprinting, having his photograph taken and being in a standard custody suite cell.
