Andrew Mountbatten-Windsor, the younger brother of Britain's King Charles III, was released from police custody on Thursday evening after a full day of questioning following his arrest on suspicion of misconduct in public office.
The former prince is still under investigation, according to UK police.
Mountbatten-Windsor was accused of being closely associated with the late U.S. financier Epstein and of sexual abuse against an underage female at Epstein's properties. He has denied these allegations, claiming that he had long since distanced himself from Epstein.
Due to the case's ongoing impact on the reputation of the British royal family, Mountbatten-Windsor was stripped of his royal and military titles in October 2025 and moved out of Royal Lodge in February this year, where he had lived for over two decades.
Newly released information shows that Mountbatten-Windsor also allegedly shared confidential government documents with Epstein.
King Charles III issued a public statement on Thursday after his younger brother was arrested, saying he received the news with "the deepest concern".
In the statement, the King said the matter "is being investigated in the appropriate manner and by the appropriate authorities", adding that "they have our full and wholehearted support and cooperation". He also stressed that "the law must take its course".
Meanwhile, there is a great deal of public attention in the UK on the former prince's arrest.
"I was quite celebratory at first. I think it's been something that's been in the news for too long," said a resident.
"Well, I think it's probably long overdue, and hopefully they get rid of the redactions from all the other people in those files and more people to come," said another.
"I think I was surprised because I didn't think it was going to happen at the point that it's happened. But I think obviously it's the right thing because it doesn't matter who you are, the law should stand to you," said a resident.
Late last month, the U.S. Department of Justice released roughly three million pages of the latest batch of the "Epstein files", along with 2,000 video segments and 180,000 images, leading to scrutiny across the Atlantic and beyond.
The disclosures have already prompted resignations among political figures over their ties to Epstein, who died under mysterious circumstances in federal custody in 2019.
