NEW YORK (AP) — Prosecutors say federal agents investigating wealthy sex offender Jeffrey Epstein found “nude photographs of what appeared to be underage girls” while searching his Manhattan mansion.

U.S. Attorney Geoffrey Berman said at a press conference Monday agents discovered the photos while executing a search warrant following Epstein's arrest Saturday on sex trafficking charges.

The 66-year-old Epstein is accused of creating and maintaining a network that allowed him to sexually exploit and abuse dozens of underage girls from 2002 to 2005. The alleged victims were as young as 14 at the time.

Messages were sent to his defense attorney seeking comment.

Epstein was arrested at Teterboro Airport in New Jersey after his private jet landed from Paris.

Epstein was taken into custody on Saturday. He is expected to appear in Manhattan federal court later Monday.

Berman said prosecutors will ask that he remain jailed pending trial, arguing he is a flight risk.
