Federal prosecutors on Monday released an indictment against billionaire financier Jeffrey Epstein, charging him with sex trafficking and accusing him of using his fortune to “create a vast network of underage victims for him to sexually exploit.”

They also revealed at a news conference that the FBI found nude photos of girls in a weekend raid of Epstein’s Manhattan mansion—after he was cuffed at a New Jersey airport following a flight from France.

“The defendant, a registered sex offender, is not reformed, he is not chastened, he is not repentant,” prosecutors wrote in a memo seeking to have Epstein jailed until trial.

“Rather, he is a continuing danger to the community and an individual who faces devastating evidence supporting deeply serious charges.”
