The stunt, organized by American lawyer Gloria Allred, sought to pressure Queen Elizabeth II’s son to reveal what he might know about the disgraced financier.
Allred represents some of Epstein’s victims and has demanded that Andrew cooperates.
The message, featuring pictures of Andrew, said: ‘‘If you see this man please ask him to call the FBI to answer their questions.’’
Andrew has stepped back from royal duties following a catastrophic BBC interview in which he categorically denied having sex with a teenager who says she was trafficked by Epstein.
Britain’s newspapers and social media commentators slammed the royal for defending his friendship with Epstein and for failing to show empathy for the convicted sex-offender’s victims.
US Attorney Geoffrey Berman told reporters in January that Andrew has provided “zero cooperation” to the FBI and US prosecutors seeking to speak with him about Epstein.
