The federal prison warden in charge when Jeffrey Epstein killed himself will soon oversee inmates again, less than six months after Attorney General William Barr reassigned him to a desk post amid probes into the pedophile’s suspicious death, according to a report.

Lamine N’Diaye will begin his new leadership role Feb. 2, at which he will assist the warden at FCI Fort Dix, a Bureau of Prisons spokesperson told CNN.

The low-security lockup in Burlington County, New Jersey, is one of the largest federal prisons in the country, with about 3,400 male inmates. The facility has an adjacent minimum-security satellite camp with another 268 inmates.

It’s unclear why N’Diaye will again be tasked with supervising inmates after Epstein’s Aug. 10 death, which has officially be ruled a suicide, riled top Justice Department officials and ended the child-sex-abuse case against him.

N’Diaye has worked at the bureau’s regional office in Pennsylvania since he was booted from the Metropolitan Correctional Center in Manhattan.

The inspector general’s investigation into Epstein’s death continues, including the question of why the disgraced financier didn’t have a cellmate.

Barr told The Associated Press in November that ­Epstein’s suicide raised “serious questions that must be answered.” He said in an interview with AP in November that the investigation revealed a “series” of mistakes that gave Epstein the chance to take his own life and that his death was the result of “a perfect storm of screw-ups.”

Two of N’Diaye’s guards at the center, Tova Noel and Michael Thomas, are accused of failing to check on Epstein every half-hour as required and falsifying reports to show they had. Instead, they browsed the web and napped while Epstein hanged himself just 15 feet away, according to prosecutors.

Noel and Thomas have pleaded not guilty to charges of conspiracy to defraud the United States and with producing false records.

Epstein’s death sparked conspiracy theories and revealed chronic mismanagement, including severe understaffing, at the prison.

Barr reassigned N’Diaye to a regional-office desk post less than two weeks after Epstein’s death and removed the acting director of the bureau, Hugh Hurwitz.
