Gardaí in Galway are investigating an act of vandalism on the constituency office of Fianna Fáil TD Noel Treacy.
The incident took place early this morning at Cross Street in Athenry.
Deputy Treacy said he was disgusted at what he described as wanton destruction, adding that he would not be intimidated by this undemocratic act.
In recent weeks, swear words were also scrawled across the front of the office.
This attack comes just weeks after eggs and stones were thrown at the Galway home of another Fianna Fáil TD, Deputy Frank Fahey.
