A demonstration has been organised against the arrest of people in connection with the Jobstown protest which saw the Tánaiste trapped in her car last November.
A total of 23 people have been held over the anti-water demonstration with no charges yet brought forward.
They claim the arrests are 'political policing' and designed to 'criminalise' anti-austerity campaigners.
Socialist TD Paul Murphy, who was himself arrested in connection with the events in Jobstown, says this Saturday's protest is about free speech.
