The woman who was thrown off the Taoiseach's car by gardai on Sunday says she intends to lodge a complaint with the Garda Síochána Ombudsman Commission (GSOC).
Fiona Healey - a member of the "Dublin Says No" anti-austerity group - was protesting against water charges outside the Mansion House in the city centre.
A video of the incident went viral when it was posted on Facebook.
Speaking on the Ray D'arcy Show on Today FM this morning, Ms Healey described what happened.
Meanwhile, more than 20 women are leading a blockade of Irish Water contractors in Donaghmede on Dublin's north side this morning.
The demonstrators, who organised their protest via social media, have been standing in the road beside the town's shopping centre since 7am this morning.
There has been no violence, but the protesters say they will stay there until the meter-installers move on.
