Murderer 'had urge to beat up prison officer'
A convicted murderer who got an "overwhelming urge to attack a blue uniform" has received a two-and-a-half year sentence for assaulting a prison officer while in jail.
Garda John Costigan accepted Brian Willoughby (40), who was convicted in 2003 of beating a man to death, has been on psychiatric medication since his incarceration 18 years ago for this and other offences.
Patrick Reynolds, defending counsel, suggested his client had given in to an overwhelming urge on the date.
Willoughby, who had an address at Orwell Park Drive, Templeogue, pleaded guilty at Dublin Circuit Criminal Court to assaulting the injured party causing him harm at Mountjoy Prison on December 31, 2017.
Willoughby's four previous convictions include murder from 2003, two assaults from 2000 and another assault in a court room in 2017.
Gda Costigan told Maddie Grant, prosecuting counsel, that the prison officer was supervising inmates during lunchtime when he felt punches to the back of his head.
