Government lawyers said in court papers Monday that Art Dulgov was removed as warden of FCI Dublin in the wake of allegations that his staff had retaliated against an inmate who testified in January in a lawsuit against the prison. The inmate was transferred to a different prison despite the judge’s order not to transfer any witnesses without court approval, filings in the case show.

An associate warden and prison captain working under Dulgov were also removed from their positions, along with an executive assistant who oversaw the prison’s minimum-security satellite camp, government lawyers said.

Since 2021, at least eight FCI Dublin employees have been charged with sexually abusing inmates. Five have pleaded guilty. Two were convicted at trial. Another case is pending.

Deputy Regional Director N.T. McKinney will replace Dulgov on an interim basis effective immediately, Bureau of Prisons spokesperson Randilee Giamusso said. McKinney is at least the fourth person to be put in charge of FCI Dublin since former warden Ray Garcia was placed on administrative leave after the FBI raided his office and vehicle in July 2021.
