EDDYVILLE, Ky. — Officials say two corrections officers have been attacked by inmates at a maximum-security prison in Kentucky.

Kentucky State Police said they were called to the Kentucky State Penitentiary in western Kentucky around 7:45 a.m. Wednesday after a corrections officer was assaulted.

Police said the incident occurred when an inmate was being removed from a room and that other inmates joined in before being restrained by other corrections officers. Two corrections officers were treated at a local hospital for non-life-threatening injuries and released.

The Eddyville prison, which houses about 850 inmates, was placed on lockdown.

The names of the corrections officers were not released.
