A prisons spokesman said the Maximum Security Unit in Tucker was "in the process of returning to normal operation" after six inmates earlier Monday snatched keys and took control of an area in the prison where three correctional officers were.
UPDATE (7:43 p.m.) According to Austin Kellerman from KARK, ADC said the six inmates "overpower [ed]" to take control of a section of Tucker Max. The inmates held three correctional officers in the area they controlled for several hours but have so far released two, the Arkansas Democrat-Gazette reported.
An inmate not directly involved in the initial situation was taken to an area hospital to be treated for injured. Since then, however, all staff have been released with only minor injuries, the Department of Corrections said.
Graves said the department's director and the state Board of Corrections would conduct their own investigation into the incident, including whether it was related to the July 22 attack. The department did not say how the prisoners took the keys from the officers, or whether the inmates had any kinds of weapons.
"The two officers were assaulted by other inmates who were attempting [to] flee the recreation area".
Around 5:30 p.m., communication began with the inmates that was labeled "positive".
Speaking to a gathering of reporters assembled near the entrance to the Tucker prison, Graves said the department would begin a "critical incident review" to determine the specific nature and cause of what happened. He said Monday's seizure took place in a recreation area separate from the site of the July altercation. At least two inmates escaped their single-man cells. From there they were able to breach the cage of a fellow inmate, who was stabbed.
Corrections officials have remained in contact with the inmates.
The Tucker Unit high security prison is located off Arkansas 15 in Jefferson County about 25 miles northeast of Pine Bluff, Ark. Then, three warning shots were fired, according to Graves.
