Updated 09:15 GMT, 19 February 2026 - Thames Valley Police confirm searches underway at multiple locations.
Arrest made at royal estate
Andrew Mountbatten-Windsor, the younger brother of King Charles III, was taken into custody early Thursday morning on allegations of misconduct in public office. Officers detained him at approximately 08:00 GMT on the Sandringham Estate in Norfolk, where he was staying. The arrest coincided with his 66th birthday.
Neither Buckingham Palace nor the King were notified in advance of the operation, which was conducted by Thames Valley Police. The force has not disclosed the specific details of the complaint but confirmed the arrest followed an assessment of alleged improper sharing of confidential documents.
Nature of the allegations
While the exact scope of the investigation remains unclear, previously reported claims suggest Mountbatten-Windsor may have shared sensitive government materials. These include reports from official trade visits, a confidential briefing on Afghanistan investment opportunities, and a Treasury document forwarded to a personal business contact.
BBC home affairs correspondent Daniel Sandford noted that the case likely involves communications with the late convicted sex offender Jeffrey Epstein. "There's an assumption that part of the focus will be on documents exchanged between Andrew and Epstein," Sandford said. However, he added that police might also be examining other materials not yet publicly disclosed, given the volume of files in the Epstein case.
"We understand the significant public interest in this case and will provide updates at the appropriate time."

Legal framework and next steps
Misconduct in public office is a complex criminal charge requiring prosecutors to prove four key elements. First, investigators must establish that the individual held a public office and that the alleged misconduct occurred within the scope of those duties. Next, they must demonstrate the suspect acted "wilfully"-either by neglecting their responsibilities or engaging in deliberate misconduct.
The third element involves proving the act constituted a serious breach of public trust. Finally, authorities must determine whether the suspect had a "reasonable excuse or justification" for their actions. This last point is critical, as it allows the accused to present their defense during the investigation.
Mountbatten-Windsor remains in police custody, though his exact location has not been disclosed. Standard procedure for such cases typically involves an initial detention period of several hours for questioning and searches. He may later be released on bail with a requirement to return for further interviews.
Police are entitled to collect a custody photograph, fingerprints, and a DNA sample during this process. If held beyond six hours, he would be transferred to a dedicated custody suite, where basic amenities such as food, drinks, and a change of clothes would be provided. Legal representation would also be made available if needed.
Ongoing searches and royal response
Thames Valley Police confirmed they are conducting searches at properties in Berkshire and Norfolk. Unmarked vehicles were observed arriving at the Sandringham Estate prior to the arrest. Mountbatten-Windsor has been residing temporarily on the estate while his permanent home, Marsh Farm, undergoes renovations.
In Berkshire, uniformed officers were seen near Royal Lodge in Windsor Great Park, Mountbatten-Windsor's former residence. BBC correspondent Helena Wilkinson reported that searches are actively underway at the property, with officers present to secure the scene.
Former Metropolitan Police Chief Superintendent Dal Babu explained that the arrest grants investigators access to electronic devices, documents, and other potential evidence. "They can search any premises he owns, occupies, or controls," Babu said, suggesting additional locations may be examined as the inquiry progresses.
King's statement and timeline
King Charles III issued a brief statement following the arrest, emphasizing the need for due process. "I have learned with the deepest concern the news about Andrew Mountbatten-Windsor and the suspicion of misconduct in public office," the statement read. "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."
"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."
King Charles III
The Crown Prosecution Service and Thames Valley Police will ultimately decide whether to press charges. Given the complexity of the case, this process could extend over several weeks. In the meantime, the royal family has reiterated its commitment to public service while refraining from further comment.
