Seven people have been arrested following disturbances after a music event on Dublin's Dollymount Strand.
Up to 15 Garda patrol cars and vans were called to the scene when fighting broke out this evening.
Gardaí say a number of officers sustained minor injuries as they tried to restore order among the crowd estimated at around 500 people.
One Garda van had its windscreen smashed.
6,000 people had earlier attended a HB MTV summer event on the beach which was described as peaceful.
