A DOG walker seen acting suspiciously around cars in UCD became enraged when stopped by gardai and told one he would "smash him around the place".
Keith Tierney (40) was "outraged" at being questioned and challenged one of the officers to a fight after his arrest, Dublin District Court heard.
Tierney, of Beech Villas, Dublin 4, denied causing a breach of the peace, garda obstruction and failing to obey their directions at the UCD campus, Belfield, last February 5.
Judge Michael Walsh found him guilty and fined him €400.
Tierney admitted having €80 worth of cannabis on him later at Irishtown Garda Station.
Gda John Altendorf said he saw the accused shining a torch into cars near college buildings.
When officers identified themselves, Tierney became aggressive, telling them to "f**k off" and that he was walking his dog.
He took up a "defensive fighting stance", Gda Altendorf said.
When arrested, Tierney tensed his arms and struggled. Asked for a lead to secure the dog, he said: "F**k off."
On his way to the station, Tierney said he wanted Gda Altendorf to stop the car so he could get out and have a "straightener".
"He stated that he would bash me no bother, he said he would smash me around the place," the garda said.
Tierney's solicitor pointed out the alleged threats after the accused's arrest were not part of the charge.
