Gardaí have released images of more than 90 people they want to speak to in connection with the Dublin riots last year.
Gardaí say these people were present in the city centre and played a role in the events which took place but they have yet to be identified.
Detectives have gathered over 17,000 hours of CCTV footage, which they say is still being reviewed following the violence in the city centre on 23 November last year.
From the analysis of this footage, gardaí have identified 99 ‘persons of interests’, who they say they want to talk to in order to either rule them in or out of the investigation.
The officer leading the investigation, Chief Superintendent Patrick McMenamin, has rejected suggestions the investigation has been too slow and insisted that gardaí have to gather the evidence and adhere to due process
The release of the images comes a year after the riots in Dublin city centre during which more than 60 shops and businesses were attacked and looted.
Buses and garda cars were burned out, transport was disrupted and 13 gardaí were injured.
Chief Supt McMenamin said that while gardaí accept the riots damaged the reputation of Dublin all over the world, it did not damage the An Garda Síochána’s reputation because, he said, order was restored within a few hours of the riots breaking out.
Gardaí also insist they will continue to pursue all those involved and have asked those who know anyone in the images or those who recognise themselves to contact them
Over 1,100 statements have been taken and more than 500 lines of inquiry have been pursued.
So far, 57 people have been arrested and more than 150 charges have been preferred.
Fourteen people have been convicted at the District Court.
Declan Donaghey, from William Street, has been convicted of arson and criminal damage and is due to be sentenced tomorrow.
Chief Supt McMenamin said if people recognise themselves they should contact gardaí, and added that he expects further arrests in the investigation.
