The unprovoked attack happened on the afternoon of September 7, 2022, when the victims were helping other staff return prisoners to their cells after yard time.
One of the guards was holding the cell door open for two of Wilson’s co-offenders when the second prisoner punched him in the face and head.
He used his pepper spray and the prisoner ran off.
As staff were trying to restrain that prisoner, Wilson approached a prisoner from behind and started throwing punches to the side of his head.
The force knocked the officer to the ground and Wilson ran off to join up with his co-offender, grabbing a plastic chair along the way.
Both prisoners faced off with staff and saw Wilson threatening to throw the chair, continually raising then lowering it.
The stand-off lasted a few minutes and more staff arrived before Wilson threw the chair and charged at the officer he’d earlier attacked.
A third prisoner then approached the same prison guard and punched him in the head several times.
All three prisoners were eventually brought under control, and the prison guard was left with blood dripping from his face.
Judge Noel Cocurullo jailed Wilson for 18 months on the charge which will be added on top of the time he was serving for burglary.
