The feds found naked photos of young girls while searching Jeffrey Epstein’s Manhattan home, prosecutors alleged Monday.

At a press conference, Manhattan US Attorney Geoffrey Berman said investigators “seized evidence including nude photographs of what appeared to be underage girls” while scouring the convicted pedophile’s mansion over the weekend.

Agents busted into the 66-year-old’s $77 million Upper East Side townhouse Saturday as Epstein was arrested on sex trafficking charges at a New Jersey airport.

In a memo, Berman alleged they found “perhaps thousands” of photos of nude and half-nude females there — including images of “at least one girl who, according to her counsel, was underage at the time the relevant photographs were taken.”

In an indictment unsealed Monday, prosecutors said they want to seize the seven-story East 71st Street property.

Epstein is accused of cultivating “a vast network” of underage girls as young as 14 whom he “sexually exploited and abused” in New York and Florida in the 2000s.
