Eight people were also arrested in Cork City for public order offences.
14 people have been arrested as Gardaí dispersed crowds of youths "loitering" in Dublin City Centre on Sunday night.
On Sunday, 6 June, An Garda Síochána put in place an extensive high visibility policing operation by uniform Gardaí supported by Public Order Units.
Gardaí on occasions engaged with crowds in Stephen’s Green, Temple Bar and South William Street based on public safety concerns and sporadic public order incidents.
A Gardaí spokesperson said in a statement that they "encountered significant numbers of groups of youths (teenage and younger adults) who were loitering around the city centre, not involved in outdoor dining/socialising."
In total, 14 people were arrested for public order offences in Dublin City Centre, including three juveniles who were released and referred for Juvenile Diversion Programme.
Four persons received an Adult Caution, and seven people were charged with Court proceedings to follow. No injuries to Gardaí were reported.
Gardaí in Cork also patrolled major amenities in the city during the day and continued to engage with local residents and businesses.
The city centre remained relatively calm through the evening with no significant incidents reported. At 11pm, following a public order incident, a decision was taken to disperse persons from Kennedy Quay.
In total, eight people were arrested for public order offences across Cork city, three directly related to incidents in Cork City centre.
"In support of Government announcements on reopening the economy and society with a specific continuing emphasis on outdoor activity An Garda Síochána will continue to patrol and manage crowds on public streets and spaces," a Gardaí spokesperson said in a statement on Sunday.
