Prince Andrew has been reportedly secretly filmed with Virginia Roberts in some sex tapes, which may link him to the underage sex slave.
The FBI agents have seized four gaudy recordings with four hours of footage each captured by the hidden cameras at Florida, where Andrew's former friend Jeffrey Epstein has his guest house, the Daily Star reported.
The agents believed that the former Wall Street financier, a registered sex offender, might have intended to try to use clippings to blackmail his rich and powerful friends including Andrew, former President Bill Clinton and scores of other politicians and businessman.
The Duke of York has strenuously denied claims that he slept with 'sex slave' girl.
Roberts has also accused Prince of participating in an orgy with her, Epstein and a group of young Russian models on the financier's private Caribbean island.
