British police are investigating claims that former Prince Andrew, now Andrew Mountbatten-Windsor, sent confidential trade reports from a 2010 Southeast Asia tour to convicted sex offender Jeffrey Epstein.

Thames Valley Police confirmed they received a report of suspected misconduct and potential breaches of the Official Secrets Act, following the release of over 3 million pages of U.S. Justice Department documents.

Prince William’s office said he was “deeply concerned” about the revelations, while the royal family continues efforts to distance itself from the scandal.

Mountbatten-Windsor, stripped of his royal titles last year, has denied wrongdoing, though correspondence shows he shared his itinerary and reports with Epstein, the AP has reported.

He has also been relocated from Royal Lodge to the king’s Sandringham estate amid growing public criticism of his privileges.
