Campaigners protesting against Shell's Corrib gas pipeline in Co Mayo attempted to blockade Shell's HQ on Leeson Street in Dublin this morning.
In a repeat of a protest last month, around 50 protesters prevented Shell staff entering the building early this morning.
Finbar Dwyer of Dublin Shell to Sea said: "We think today was a successful protest to highlight the €51 billion giveaway of Ireland's resources.
"If the state took a reasonable share of the estimated €51 billion revenue from the Corrib gas field, think what that money could do for health and other public services. A proper salary could be paid to all public servants, not just nurses."
Mr Dwyer said that despite the protest being "peaceful and non-violent", the protesters were "forcibly removed by gardaí".
A Garda spokesman said there had been no arrests made at the demonstration.
A spokeswoman for Shell E&P Ireland told ireland.comthat the comapny "fully recognises the right to peaceful protest" but that Shell employees had "a right to go to work".
"The company recognises that a minority of people are opposed to the Corrib project and have genuine concerns. However, the company has sought to address these concerns by a number of means, including mediation and our agreement to modify the onshore pipeline route," she said.
The spokeswoman also pointed out that the project has also just been through a detailed EPA oral hearing during which objectors had the opportunity to again voice their concerns.
