Ninety people were arrested over the weekend at the annual Oxegen music festival.
Eight people were detained for assault while 21 were taken into custody over public order offences, according to Gardai figures.
There were more than 300 drug seizures, with 28 people arrested under section 15 of the Misuse of Drugs Act for dealing drugs.
Over the weekend, 1,450 drivers were breath-tested at mandatory alcohol-testing checkpoints. As a result, 15 people were arrested for suspected drink-driving.
There were also 12 people detained for theft, three for road traffic offences and three for other offences.
However, there has still been no arrests over an incident in which five teenagers suffered slash wounds during a row at one of the campsites in Punchestown, Co Kildare, shortly after 4am on Saturday.
One of the men, a 19-year-old from Co Tyrone, was treated in hospital after being stabbed in the neck, although his injuries are not thought to be life threatening.
The four other young men were treated on site for slash wounds to their faces and arms. Three of them are from Co Derry and the other is from Co Wexford.
Around 80,000 attended the three-day festival, with acts including Beyonce, Coldplay, Foo Fighters and Paolo Nutini.
Gardai said the vast majority of those attending caused no trouble.
