Three members of An Garda Síochána were hospitalised and 23 arrests were made during a second night of public disorder in Dublin on Wednesday night.
Gardaí told The Irish Times that 23 were detained following the disturbances near the Citywest Hotel in Saggart.
Members of the force are believed to have been injured on the wrist, the head and forearm, with one suffering a dislocated shoulder. One garda was struck on the head with a bottle.
Gardaí said in an earlier statement on Wednesday night that a number of individuals were arrested, mainly for public order offences.

The disturbances were mainly carried out by young adult men and teenagers, the force said.
Rioters threw masonry, flares, glass bottles and wooden planks at gardaí near the hotel, which is used to house asylum seekers.
Some 500 people were estimated to have taken part in the disturbances.
More than 300 gardaí were deployed to deal with the disorder. The Garda water cannon was on standby but its use was not deemed necessary.
It was the second night of violence in the area following an alleged sexual assault on a 10-year-old girl in the vicinity of the hotel early on Monday morning.
In a statement Minister for Justice Jim O’Callaghan praised An Garda Síochána for its response to “thuggish violence” in the area.
Those arrested “will be charged, named and dealt with relentlessly by our criminal justice system”, he said in a statement on Wednesday night.
The Garda public order unit set up a cordon at the junction of Garter Lane and Citywest Drive. A mounted unit and a dog unit attended the scene with a Garda helicopter providing air support.
Earlier on Wednesday, Garda Commissioner Justin Kelly said there will be a “robust response” to any continued disorder following a night of violence on Tuesday.
Mr Kelly said a further gathering outside the hotel had been proposed on social media.
A number of public transport services to the area were suspended again including the Luas red line between Belgard and Saggart and the number 69 Dublin Bus.
On Tuesday night, gardaí were attacked with missiles and fireworks after violence flared outside the hotel. A Garda vehicle was also set on fire during the unrest.
A woman garda injured during the violence on Tuesday has since been discharged from hospital.
Mr Kelly, who visited the scene on Wednesday in the aftermath of the initial violence, told reporters he is “determined” that further people will be “brought before the courts to face justice”.

He said the disorder on Tuesday night was not a peaceful protest.
“I can promise that we will have a robust response again to any further disorder.”
Nearly 300 members of An Garda Síochána were on duty in response to the public disorder.
This included more than 125 uniformed gardaí, 150 members of the public order unit and a water cannon. Mounted and dog units also attended, supported by members in the air support unit.
A senior officer has been appointed to investigate the rioting.
On Wednesday morning, shattered glass, a torn-down public bin and piles of bricks lay strewn across Garter Lane outside the centre.
A few metres away, the Garda van set alight by a mob the night before was being removed by a tow truck.
The disorder on Tuesday night involved up to 1,000 people, with six arrested following the disturbances.
On Wednesday afternoon, Taoiseach Micheál Martin praised gardaí for their “bravery, courage and professionalism” in dealing with the riot in Citywest on Tuesday night.
Mr Martin said in the Dáil, gardaí “come from our community and are there to protect us all”. It “beggars belief” that people would “articulate such vile abuse” and “then attack them in a very serious way”, he said. – Additional reporting PA
