Gardai have arrested a further four people in connection with last November's water protest in Jobstown in which the Tánaiste was trapped in her car for over two hours.
One of those detained is a juvenile male.
Two men and a woman aged in their 20's and 30's were also arrested in the Tallaght area shortly before 7 this morning.
They are being held at Tallaght and Rathfarnham Garda Stations where they can be questioned for up to 24 hours.
