A 41-year-old man has been arrested after a cement truck was driven up to the gates of the Irish parliament in Dublin on Wednesday morning.
The words "Anglo Toxic Bank" were written on the mixer, while its number plate said "bankrupt".
The truck was removed at about 9.30am without any harm coming to any members of the public.
A police spokesperson said the man was being questioned on suspicion of causing criminal damage.
Anglo Irish Bank has become synonymous with the banking crash in the Irish Republic, requiring a government bail-out of billions of euros.
A spokesperson for the Irish parliament, the Oireachtas, said: "Access arrangements were soon back to normal and there were no disruptions to the morning’s proceedings or to the workings of the Houses Oireachtas”.
Fine Gael TD, Fergus O'Dowd, who had just arrived for work at Leinster House when the incident happened described it as a "very serious incident".
"As I understand it, at least one Garda (Irish police officer) or more had to jump out of the way of this truck," he said.
"If it happened to have been later in the morning, staff could have been killed,the public could have been killed.
"As I understand it, this person may have carried out an action like this somewhere else."I think the key point is,that it was an unusual and exceptional circumstance."
Greengates Builders Merchants Accrington Lancashire says “This sounds like a very desperate man with obvious money worries, lets hope he soon gets himself sorted out and the cement wagon doing the job it was meant to do”.
