Metropolitan Police officers were instructed to provide security for a dinner party at Jeffrey Epstein's New York home attended by Andrew Mountbatten-Windsor, according to emails released by the US Department of Justice.
The Met says it has not identified any wrongdoing by its protection officers "at this time". On Friday, the force said it is "identifying and contacting" former and serving officers who may have relevant information.
As a senior working member of the Royal Family at the time, the then Prince Andrew would have been accompanied by close protection officers as part of his security.
Andrew has always strenuously denied any wrongdoing.
In a statement to the BBC, the Met said that protection officers were held to the same high standards of professional behaviour as all police officers.
