The Florida lawmaker who urged Gov. Ron DeSantis to open a probe into wealthy pedophile Jeffrey Epstein’s cushy 2008 jail setup says she’s been getting threats warning her to back off.

State Sen. Lauren Book has reached out to Capitol Police after receiving more than a dozen calls from menacing supporters of Palm Beach Sheriff Ric Bradshaw, who handled Epstein’s lenient “work release” program, The Miami Herald reported Thursday.

“I’ve received countless phone calls saying ‘Little girl you don’t know what you’re getting into’ and telling me that I should just stop,’’ Book said.

In a statement, the Palm Beach Sheriff’s Office said it didn’t know of anyone trying to threaten or pressure Book.

The Democratic state senator Monday wrote a letter to DeSantis asking him to authorize an investigation into how Epstein, a registered sex offender, was allowed to stroll out of the Palm Beach County Jail for nearly every day of his 13-month prison sentence and go to a private office on a “work release” program.

A lawyer for several of Epstein’s accusers claimed last week that the politically connected perv had “improper sexual contact’’ with women while supposedly working at his office under the deal.

“If Epstein was able to abuse young girls while under supervised work release, we need to understand very clearly when and how these egregious lapses and abuses occurred so they cannot be repeated,” Book, a vocal advocate for child sex abuse victims, wrote in her letter.

The Republican governor Thursday said he would “certainly consider” an investigation but hasn’t decided yet how the state should respond.

“I saw someone sent me a letter. I looked at it. I’ve got to figure out what the proper role of FDLE [the Florida Department of Law Enforcement] is,” DeSantis said. “I know they are investigating it down in Palm Beach. … Clearly, when you look at how that happened, if even like 10% of the things about him are true, then that whole agreement was obviously suspect and willfully below what he should have faced.”

Bradshaw announced last week that he would conduct an internal investigation into reports that Epstein, 66, was allowed female visitors in his office.

Lawyers for Epstein’s victims say it’s ludicrous to think Bradshaw would be able to investigate his own department.

“The allegations are against the sheriff, and there’s no way a credible investigation can be conducted by the sheriff’s office when the allegations extend to the very top of the organization,’’ said lawyer Jack Scarola.

The threats against Book came as Epstein was found injured and nearly unconscious in his cell at the Metropolitan Correctional Center in Manhattan, where he is awaiting trial on sex trafficking charges.
