A video has emerged from yesterday's anti-water charge protests which appears to show a vehicle colliding with at least one pedestrian.
Gardaí have confirmed that at least one person was taken to hospital following the incident.
A number of protesters had blocked traffic as they gathered at the junction between Eden Quay and Customer House Quay, just outside Liberty Hall,
Eyewitnesses reported that the SUV allegedly mounted the path and later sped off.
Meanwhile, organisers of yesterday's anti-water charge demonstration hailed the protests as a success.
Gardaí say 30,000 plus attended the Right2Water demonstration on Merrion Square. Organisers said the figure was closer to 80,000, with others estimating more than 100,000 people were in attendance. The Irish Times, using the CrowdSize App, estimated the protest size at 32,000.
Another national rally is planned for January 31.
Meanwhile, six people arrested during yesterday's protests in Dublin have been released without charge.
Although the protest was generally peaceful, a number of arrests were made for public order offences.
Four were detained on O'Connell Bridge, when gardaí had to move protesters who were blocking traffic last night.
After the main event - which passed off without incident - finished outside the Dáil at Merrion Square more protests developed at the end of Kildare Street. One garda was hospitalised after being struck by a missile and two people were arrested for public order offences.
