In July, Epstein was arrested for sex trafficking charges in Florida and New York.
The Duke of York was named in US court papers by Virginia Giuffre - formerly known as Virginia Roberts - who accused the tycoon of keeping her as a "sex slave."
According to Giuffre, Epstein forced her to have sex with Prince Andrew three times when she was just 17 years old.
Andrew - who was previously married to Sarah Ferguson - has denied the allegations, and has disputed a notorious photo of himself with his arm around the then teen.
A US judge struck out Ms Giuffre’s claim against Prince Andrew in 2015, labelling it “immaterial” and “impertinent.”
The Duke of York released a statement condemning the disgraced millionaire, while Buckingham Palace said Prince Andrew would help authorities in any investigations.
