article: An inmate at an Arizona jail left one officer hospitalized with brain bleeding and broken bones in his face after a psychiatric ward assault. The 18-year-old, who was booked into Lower Buckeye Jail in Phoenix two weeks ago, is seen on surveillance video walking in a room he was not authorized to be in before being approached by two officers. Maricopa County Sheriff Joe Arpaio said that the two jail employees began telling the young man to go back to his cell before he began taking swings at them. Scroll down for video . An assault on an officer at a jail in Phoenix has left one officer in intensive care with brain bleeding. Above, the inmate is captured on video in a psychiatric ward area where he is not authorized . Officers including Scott Beaty (center) approached the unidentified 18-year-old inmate and told him to go back to his cell . The inmate then began punching Beatty and the other officer in the room, who used a Taser but could not subdue the young man . The unnamed inmate, who was not immediately affected by four taser shots, was eventually subdued by a large group of officers who came to the scene. Three detention officers were taken to a nearby hospital, and two of them had been knocked unconscious. Scott Beaty, a 15-year-veteran, was taken to the intensive care unit and will need reconstructive surgery after suffering a brain bleed and broken bones in his face. The inmate, who did not have any prior incidents of bad behavior, was not injured. After knocking Beaty to the ground, the inmate is seen attacking the other officer, who was also taken to a nearby hospital . More officers arrived on the scene where the assault took place, though additional taser shots did not immediately affect the 18-year-old . The unidentified inmate was eventually subdued by a group of officers, who saw their colleague knocked out on the ground after being hit repeatedly . 'Sometimes when you have a mental condition you fight and get super mad,' Arpaio said during a press conference, though he did not elaborate on the mental condition. Arpaio said he could not speculate on what led to the attack. The prisoner became 'very violent' according to officials, and was reportedly fighting until he was put in lock down in the psychiatric ward, where he remains. He will only be allowed out for one hour a day. Though he was booked into Lower Buckeye for a minor felony charge, the prisoner will now face aggravated assault charges. Arpaio said that there have been 178 incidents of assault at his county's jails in the last 12 months. Beaty was taken to the intensive care unit after the incident, where he suffered broken bones in his face and brain bleeding . Three of four officers injured in the attack went to the hospital. The inmate was not injured during the incident .
