What we know about former Prince Andrew's legal action against police

King Charles' younger brother Andrew Mountbatten-Windsor, 66, has initiated legal proceedings against UK police following his arrest earlier this year on suspicion of misconduct in public office. The arrest, which took place on his 66th birthday at his brother's Sandringham estate in Norfolk, England, was prompted by revelations from the Epstein files in the United States.

Mountbatten-Windsor has requested a judge to determine if Thames Valley Police's actions were lawful. He has lodged a judicial review concerning the search warrants executed at his properties at Sandringham Estate and Royal Lodge in Windsor. A court hearing is scheduled for Thursday, according to British media reports. Thames Valley Police has confirmed to CNN that it is "engaged in legal proceedings in relation to warrants previously obtained from the Central Criminal Court" and declined further comment due to ongoing legal proceedings. CNN has contacted the UK Judicial Office for additional insight.
