AN OFF-duty garda who heard a window smash while he was in his back garden ran upstairs and saw two men riffling through a neighbour's car, a court heard.
Shane McLoughlin (20) had denied causing the damage, and claimed he was getting a lift home after a house party.
Judge David McHugh imposed a two-month sentence.
McLoughlin, of Foxdene Green, Clondalkin, was found guilty of criminal damage and possession of articles for use in a theft at Rossberry Avenue, Lucan, last May 30.
A bench warrant was issued at Blanchardstown District Court for his alleged accomplice after he failed to appear.
The off-duty garda said he was in his back yard when he heard a window breaking. He ran upstairs and saw two men had broken into a Toyota Avensis and were riffling through it.
The driver's window was smashed and the damage to the vehicle was €550.
The officer said the men got into a red car and drove in to Rossberry Court, where gardai stopped them.
Gda Cormac O'Lavin said he searched the car, a red Skoda Fabia, and found seven screwdrivers, a crowbar, a claw hammer and disposable gloves.
McLoughlin claimed he had been at a party and he had asked a friend to collect him.
He denied smashing the window of the Toyota, saying he never left the red car. He also claimed he did not know the tools were in the car.
McLoughlin immediately appealed against the decision.
