Washington (CNN) Attorney General William Barr removed the acting head of the Bureau of Prisons, the Justice Department said Monday, replacing the agency's top official in the wake of the suicide of Jeffrey Epstein earlier this month.

In a statement, Barr said Hugh Hurwitz, who had served in the acting position since last year, would return to the assistant director position he formerly occupied.

Dr. Kathleen Hawk Sawyer, who led the bureau from 1992 to 2003, will be the new director, Barr said.

Barr has said he was "appalled" and "angry" to learn of the suicide, and cited "serious irregularities" at the Manhattan facility where Epstein had been detained.

Barr had already shaken up the top leadership at the Metropolitan Correctional Center in New York, announcing last week that the facility's warden would be reassigned while the FBI and Justice Department's inspector general investigated the conditions leading up to the suicide.
