A court has heard that the man accused of murdering Detective Garda Colm Horkan claimed that he had been attacked by him and said: "With all that's going on with the police in this world, I shot him."
In the Central Criminal Court today, Prosecution Senior Counsel Michael Delaney opened the trial before the jury of seven men and five women.
Motorbike mechanic Stephen Silver, from Aughavard, Foxford, Co Mayo, has pleaded not guilty to the murder of Det Garda Horkan.
But the 46-year-old has pleaded guilty to manslaughter by reason of diminished responsibility.
