The Health Minister says the public disorder on Dublin streets last night was "thuggish" and "completely unacceptable".
It follows another night where large crowds of young people gathered to socialise in the South William Street, Stephen's Green and Temple Bar areas.
Five teenagers were among 14 people arrested for public order offences in Dublin last night.
Gardai had glass bottles and other missiles thrown at them, as they attempted to disperse crowds in the South William Street, Stephen's Green and Temple Bar areas.
One officer was hospitalised with a leg injury while a patrol car was also damaged.
Meanwhile, Gardai say there were no major public order incidents in Cork, Galway and Limerick last night.
