TWO men were arrested after they halted drilling work by Shell in Sruwaddacon Bay last week.
On Wednesday afternoon three members of the Rossport Solidarity Camp mounted one of the drilling platforms at low tide.
They remained there all night and were provided with food and water by other protesters.
There was no drilling work being carried out at the time and gardai did not intervene.
However, on Thursday morning drilling work was scheduled to resume. A garda water patrol moved in at around 7am and requested that the protesters leave the platform.
One man left of his own accord but two men in their twenties, who are not from the locality, had to be arrested and removed.
They were later released without charge and a file is being sent to the Director of Public Prosecutions (DPP) on the matter.
This is the fourth arrest for such activity in as many days. Two protesters were arrested near the same drilling platform on Monday week last.
The protests coincide with the ongoing An Bord Pleanála oral hearing into Shell’s onshore pipeline planning application which is continuing at the Broadhaven Bay Hotel in Belmullet.
