(CNN) The former warden of the New York prison where Jeffrey Epstein died last year is getting a new job at another federal penitentiary as federal authorities continue investigating the multimillionaire's death, a Bureau of Prisons spokesperson told CNN.

Lamine N'diaye , the former warden at the Metropolitan Correctional Center in Manhattan, has been assigned to a leadership position at Federal Correctional Institution, Fort Dix, a large low-security prison in Burlington County, New Jersey, the spokesperson said.

He is expected to start as soon as next month in a role assisting the prison's current warden. The Associated Press was first to report on N'diaye's new role.

Last year, Attorney General William Barr ordered N'diaye to be temporarily moved to a Bureau of Prisons regional office in Philadelphia. Barr said in August that there were "serious irregularities" at the Manhattan prison.

Epstein, 66, died in jail August 10 while he was waiting to be tried on federal charges of running a sex trafficking ring of underage girls, some as young as 14 years old. His death was ruled a suicide.
