LITTLE ROCK, Ark. - All of the three correctional officers who had been held by prisoners at a maximum security prison in Arkansas have been released.

  

Correction Department spokesman Solomon Graves said the last of the three staff had been released about three hours after six inmates snatched keys from them and controlled an area of the Maximum Security Unit at Tucker. Two of the three officers had been released earlier Monday evening.

  

Graves did not provide any details about the inmates who took the keys and held the officers. An inmate who had not been involved in the initial disturbance was taken to the hospital earlier Monday with injuries.
