The Federal Bureau of Investigation is looking into an attack on a correctional officer at the federal prison in Lee County, Virginia.
A spokesman for the U.S. Department of Justice's Federal Bureau of Prisons says the incident happened just before 8 a.m. Sunday.
That same spokesman told News 5 that the staff was able to contain the situation after an inmate apparently attacked the correctional officer.
The prison is on lockdown while the incident is investigated.
The officer was treated for some injuries and released from the hospital.
