A prisoner who attacked an officer inside Highpoint Prison has been sentenced to 30 weeks in custody.
Reiss Kirby, 25, had been due to stand trial at Ipswich Crown Court this week accused of inflicting grevious bodily harm.
Before the trial began yesterday, (Tuesday) Kirby, currently being held at HMP Peterborough, pleaded guilty to a charge of assault causing actual bodily harm to Senior Prison Officer Stephen Fry.
Lori Tucker, prosecuting, said that the Crown Prosecution Service accepted the guilty plea and would offer no evidence on the charge of causing grevious bodily harm.
Kirby carried out the attack on Mr Fry on May 31 last year inside the prison at Stradishall.
Noel Casey, defending, said that Kirby regretted having caused the incident.
Sentencing him, Mr Recorder Charles Makey said he would formally record a verdict of not guilty to assault causing grevious bodily harm but imposed a 30 week prison term for the actual bodily harm offence.
