INEZ, Ky. (AP) - A federal penitentiary in eastern Kentucky was on lockdown Monday after an inmate assaulted four staff members, prison officials said.
The attacked happened at about 5 p.m. Sunday at United States Penitentiary-Big Sandy, a high security facility in Inez, according to a statement from the facility. The statement did not include details of what happened. Robert Ranum, a spokesman for the prison, did not immediately return calls seeking comment.
The injured workers, who were not identified, were taken to area hospitals for treatment, the statement said.
David Beyer, a spokesman for the FBI in Louisville, said the agency was investigating but he had no further details.
The prison, which opened in 2003, houses male inmates and has reported other outbreaks of violence.
In 2006, two inmates were stabbed to death within 20 days of each other. Calvin Speight, 42, died Oct. 24, 2006 after being stabbed several times in the neck. Shamoni Peterson, 32, died Nov. 13 from similar wounds.
