The Department of Corrections has launched an internal investigation after a second corrections officer was assaulted by an inmate.
Director Samantha Brennan confirmed an attack happened around 9:18 a.m. Wednesday. A detainee allegedly punched a corrections officer multiple times.
"The officer was taken to the Guam Memorial Hospital to be treated for minor injuries. As a result of the incident, restrictions on the whole compound was initiated and all visitations have been canceled for the remainder of the day. The assault has also been reported to the Guam Police Department," Brennan stated in a release late Wednesday afternoon. "The department takes this matter seriously and will continue to ensure the safety and protection of all its officers, staff and everyone within its custody."
The incident, which occurred at the prison's Post 6 maximum-security unit, led to a lockdown of the facility.
The Guam Daily Post confirmed that the detainee suspected in the assault is Mitch Bronson Martinez, who was being held on charges of attempted murder in connection with a 2016 fight at Club Foxy's in Tumon.
There is no word on whether Martinez will face additional charges following Wednesday's assault.
This was the second attack on a corrections officer reported in the past few days.
On Sunday, detainee Bryan Matheus was arrested and charged with assault on a peace officer as a third-degree felony.
Court documents state Matheus punched and kicked a corrections officer multiple times in the leg, face and head at the prison's Post 5 unit.
The officer suffered bruising and swelling and was treated for his injuries at Guam Memorial Hospital.
Documents state Matheus told police the officer hit him first in the chin and neck, but authorities noted Matheus had no redness or bruising.
An internal investigation is ongoing in that incident as well.
