Four people have been arrested during a protest by Shell to Sea campaigners in Co Mayo.
A Shell to Sea spokesman said 50 people were involved in the demonstration today on Glengad Beach.
He said one of those arrested is the son of Maura Harrington, who is on the fifth day of a hunger strike.
A Garda spokesman said three men and a woman were arrested this afternoon for public order offences.
All four are being held at Belmullet Garda station.
Ms Harrington (54) has said she will continue her hunger strike until the boat brought in by Shell to lay the Corrib offshore gas pipeline leaves Irish waters.
Shell said earlier this week pipelaying has been suspended due to "technical issues" on board the boat, the
Solitaire.
The 300-metre boat, the largest pipe-laying vessel in the world, has returned to Killybegs, Co Donegal, where a full assessment of the damage is under way.
