British police officers involved in royal protection are set to be grilled as part of a review into Andrew Mountbatten-Windsor, as authorities probe information on "anything they saw or heard".
Mr Mountbatten-Windsor, a son of the late Queen Elizabeth II and brother to King Charles III, was arrested at his Norfolk home on Thursday, local time, on suspicion of misconduct in a public office.
On Friday, London's Metropolitan Police — more commonly known as the Met — announced it was contacting former and serving officers "who may have worked closely, in a protection capacity" with Mr Mountbatten-Windsor.
"They have been asked to consider carefully whether anything they saw or heard during that period of service may be relevant to our ongoing reviews and to share any information that could assist us," a statement read.
Mr Mountbatten-Windsor has faced criminal allegations for years, which he denies.
His arrest on Thursday was not related to accusations he raped a 17-year-old child who had been trafficked to him by the late sex offender Jeffrey Epstein in London 25 years ago.
"While we are aware of the extensive media reporting and commentary about this matter, as of today, no new criminal allegations have been made to the Met regarding sexual offences said to have occurred within our jurisdiction," the police statement released on Friday read.
"We continue to urge anyone with new or relevant information to come forward.
"All allegations will be taken seriously and, as with any matter, any information received will be assessed and investigated where appropriate.
"The action outlined above is independent of investigations or assessment work being carried out by other forces."
At least nine police forces in the United Kingdom are reviewing or have launched investigations into accusations made against Mr Mountbatten-Windsor.
The 66-year old stepped back from royal duties in 2019 over the allegations, and later reached a multi-million pound out-of-court settlement with his accuser, who died by suicide in Western Australia last year.
He was last year stripped of his royal titles.
Mr Mountbatten-Windsor has faced allegations he asked his royal protection team to dig up dirt on his accuser, Virginia Roberts Giuffre.
Ms Roberts Giuffre's claims have been investigated by the Met on multiple occasions, but the former royal has never been charged.
Also on Friday, the Met announced it was reviewing claims London airports may have been used to "facilitate human trafficking and sexual exploitation".
"We are assessing this information and are actively seeking further detail from law enforcement partners, including those in the United States," their statement read.
While that development is linked to the Epstein files, about half of which were released by the US Justice Department earlier this year, it is separate to the review into Mr Mountbatten-Windsor.
The former royal's arrest on Friday was related to allegations sparked by emails in the Epstein files.
Mr Mountbatten-Windsor has been accused of sharing sensitive UK government information with Epstein during his time as a trade commissioner. He held that role for about 10 years from 2001.
Police released him after about 10 hours on Thursday, although their investigation continues.
