Four men arrested this morning over the Joan Burton car protest have been released without charge.
The anti-water charges demo saw the Tanaiste trapped in her car for over 2 hours last November.
Todays arrests bring the total number of people picked up this week to 12.
Four people including a 16 year old were arrested yesterday and four others including TD Paul Murphy was detained on Monday.
They have all been released without charge.
