Minister for Justice Alan Shatter has told the Dáil that anti-social behaviour at last Saturday's concert in the Phoenix Park is of major concern to him.
Gardaí say that following the concert, there were 33 arrests and 70 charges of public order, drunkenness and drug-related offences being brought before the courts.
Mr Shatter said he believes the level of security at the concert, based on the “nature” of the event, was inadequate.
Speaking in the Dáil this afternoon during topical questions, Labour TD Eamonn Maloney said he was astonished that the directors of MCD had not been arrested following the violence at the concert.
He claimed that in the UK or Europe they would have been.
Deputy Maloney accused the promoters of being involved in a PR campaign to disclaim responsibility for what had happened.
He told the Dáil that the controversy reminded him of the 1981 Stardust tragedy where no one was ultimately found responsible for what had happened.
Deputy Maloney said MCD should not be awarded any more concert licences.
