Andrew Mountbatten-Windsor faces a fresh police probe as officers investigate allegations that Jeffrey Epstein trafficked women to Balmoral.
Police Scotland has confirmed enquiries into stays at the King's Highlands estate by the late convicted paedophile and his former girlfriend Ghislaine Maxwell, who is in jail in the US.
Mr Mountbatten-Windsor and Maxwell are said to have flown to Balmoral in 2006 on a private jet owned by Epstein.
US prosecutors had previously shared a picture of Epstein and Maxwell at a Balmoral log cabin, taken during a trip to Royal Deeside in 1999.
Photos also released by the Department of Justice in the US appear to show Mr Mountbatten-Windsor and Epstein on a shooting trip at the estate.
Police Scotland said: 'We have received information and active enquiries are ongoing, but these are at a very early stage.
'All enquiries are evidence led, with the needs of victim survivors at the heart of those enquiries.

'We would never confirm details of ongoing enquiries and it would be inappropriate to comment further.'
Forces including Thames Valley Police, the Metropolitan Police and Surrey Police have live investigations linked to the release of the Epstein files, the National Police Chiefs’ Council (NPCC) confirmed.
The NPCC said: 'Identifying any further potential offending, suspects, victims or witnesses is a complex process and will take time, but UK policing remains committed to carrying out a meticulous assessment of the material released by the US Department of Justice.'
There is not currently a national investigation, the NPCC said.
The former Duke of York was arrested on suspicion of misconduct in public office on February 19, his 66th birthday, following allegations that he shared sensitive information with Epstein during his time as the UK’s trade envoy.
Mr Mountabatten-Windsor was interviewed under caution before being released under investigation, and denies wrongdoing, with the police probe ongoing.
Buckingham Palace announced last year that he would no longer be known as a prince and would leave his home at Royal Lodge in Windsor to take up residence at the Royal Family's Sandringham Estate in Norfolk.
The King stripped his brother of titles after weeks of pressure to act over his relationship with late financier and convicted paedophile Epstein.

That came after the former prince said he would no longer Epstein victim Virginia Giuffre in her posthumous memoir.
Ms Giuffre, who took her life in April last year, alleged she was forced to have sex three times with Mr Mountbatten-Windsor, which he vehemently denies, including when she was 17 and during an orgy, after she was trafficked by Epstein.
Mr Mountbatten-Windsor paid millions to settle a civil sexual-assault case with her in 2022, despite insisting he had never met her.
Ms Giuffre had previously told how Epstein and his accomplice Maxwell kept her as a sex slave while flying her around the world and offering her to their powerful associates 'like a platter of fruit'.
A photograph has been widely shared of them together in a London townhouse, the then prince's arm around her bare midriff, and was included in Ms Giuffre's lawsuit against him.
Epstein killed himself in August 2019 while awaiting trial on federal sex-trafficking charges involving dozens of teenage girls and young women, some as young as 14.
In lawsuits, Ms Giuffre said she was a teenage spa attendant at Mar-a-Lago, President Donald Trump's Palm Beach club, when she was approached in 2000 by Epstein's girlfriend and her later employer, Maxwell.
Ms Giuffre said Maxwell hired her as a masseuse for Epstein, but the couple effectively made her a sexual servant, pressuring her into gratifying not only Epstein but his friends and associates.
Buckingham Palace said in a statement last October that the King's moves against his brother were 'deemed necessary notwithstanding the fact that he continues to deny the allegations against him'.
The statement said: 'His Majesty has today initiated a formal process to remove the style, titles and honours of Prince Andrew.
'Prince Andrew will now be known as Andrew Mountbatten-Windsor. His lease on Royal Lodge has, to date, provided him with legal protection to continue in residence.
'Formal notice has now been served to surrender the lease and he will move to alternative private accommodation.
'These censures are deemed necessary, notwithstanding the fact that he continues to deny the allegations against him.
'Their Majesties wish to make clear that their thoughts and utmost sympathies have been, and will remain with, the victims and survivors of any and all forms of abuse.'
Officers have been investigating Mr Mountbatten-Windsor for alleged misconduct in public office, after it was suggested that emails he sent to convicted sex offender Epstein while he was the UK's trade envoy contained sensitive information.
As plain-clothes officers searched his property earlier this year, the former prince was arrested and held for almost 12 hours at Aylsham Police Station in Norfolk while he was being questioned.
He was released under investigation and strongly denies any wrongdoing.
It was the first time a royal had been detained by police in more than 350 years.
