Tommy Mannah pleaded guilty to dangerous driving and use of an imitation firearm.
Detective Sergeant Kieran O’Sullivan told the court how at 11.30 pm on the night of July 3rd, 2020, Gardaí received a call about a man attempting to break into a car and possessing a firearm.
"Gardaí attended at the scene. Tommy Mannah returned with an alleged handgun which he discharged in the direction of Gardaí, hitting Sgt. Greenway in the arm. He then got into the car and drove from the scene."
Sgt. O'Sullivan continued "He was signalled to stop and he failed. He discharged shots out the window of the car. He crashed through a barrier at the toll plaza. A stinger was placed on the motorway. Armed support unit members approached and identified themselves as armed Gardaí. He discharged shots at the armed Gardaí. A Tazer was discharged and he was successfully arrested. This was observed by a number of witnesses from Gardaí at Military Road to the M8 motorway. Gardaí never lost sight of him during this."
Senior Counsel Siobhán Lankford said the accused "is currently on anti-psychotic medication. There was nothing like this before from him and nothing since. It was an extraordinary incident."
Judge Seán Ó Donnabháin remanded Mannah in custody for sentencing on September 20th.
