The protests outside the Dáil are building ahead of the toughest Budget in living memory.
There is a heavy garda presense around Leinster House following an earlier incident where a man drove a cherry-picker truck up Kildare Street to the gates of the Dáil.
Shortly after 7.30am this morning a man parked a cherry picker covered with a number of slogans attacking politicians and the banking sector on Kildare Street.
He raised himself to a height and remained there for a time before lowering it down at around 8.30am
He was then arrested by gardaí and taken to Pearse Street Garda Station.
Authorities are preparing for a day of demonstrations, with left-wing groups, students and community organisations all planning to picket the area this evening and tonight.
