Three men have been arrested after they were caught graffitiing a number of Irish Rail carriages.
A special inter-agency operation had been established recently by Gardaí in the Dublin Metropolitan Region and Iarnród Éireann.
It was in order to target the grafitti artists who were causing criminal damage to carriages on the North Dublin train line.
As part of this operation Gardaí conducted patrols of rail lines over the past weekend in an effort to target groups involved in this activity.
While on patrol on Sunday afternoon, a number of people were detected spraying graffiti on a train carriage at Clontarf Train Station.
Three males, aged in their 20s, were apprehended by Gardaí and arrested.
They were taken to Clontarf Garda Station where they were detained under Section 4 of the Criminal Justice Act, 1984.
All three have since appeared before the courts charged in connection with the case.
A Garda spokesperson said: "Graffiti resulted in carriages being removed from service for a time & costly repairs."
The investigation is ongoing.
