Ibraham was serving time for first-degree robbery, vehicular assault, car theft, and DUI. He has been transferred to the Washington Corrections Center in Shelton, Barclay said.
After the attack, the prison was put on lockdown while cell searches and integrity checks were made.
Barclay said this appeared to be an isolated incident, and local law enforcement is continuing the investigation.
FORKS — A Clallam Bay Corrections Center officer who suffered serious head injuries last week continued to improve but remained hospitalized Monday.
Correctional Officer Terry Breedlove remained at Forks Community Hospital and will remain there until he can walk, according to his family.
“He’s going to be here longer, I think,” said Breedlove’s mother, Joanne Spaulding.
Breedlove suffered a brain injury during an attack Jan. 25 by inmate Abdinjib Ibraham, 28, of King County, investigators said.
An MRI was performed on Breedlove on Saturday. It showed injuries to two vertebrae, Spaulding said.
Breedlove can stand but experiences difficulty once standing, she said.
The prison, which holds 900 inmates, went on lockdown after the attack and remained on lockdown Monday.
Inmates are confined to their cells and there is no visitation.
Ibraham said “Allahu akbar” (an Islamic phrase meaning “God is greater”) twice — once when he hit the guard, and again after the attack, said Brian King, chief criminal deputy for the Clallam County Sheriff’s Office.
Deputy Ed Anderson, the West End supervisor for the Sheriff’s Office who is in charge of the investigation into the attack, said he spent most of Monday interviewing witnesses in the prison.
“We’re still gathering information,” Anderson said.
Breedlove was on duty in a medium-security portion of the prison when he was attacked, Anderson said.
Ibraham had pried a round metal seat off a stool in a cell and repeatedly hit Breedlove over the head with it until other inmates stopped the attack, investigators have said.
Security cameras were not working at the time, investigators have said.
Prison officials said the cameras have since become operational.
Ibraham, who was serving a King County sentence for four counts of vehicular assault, driving under the influence, second-degree taking a motor vehicle and first-degree robbery, has been transferred to Walla Walla.
