DOZENS of people were arrested and drugs were seized during four concerts at Dublin's Marley Park this summer, the Herald can reveal.
There were 32 arrests at the gigs, which included appearances by rappers Kanye West and Macklemore.
Seventy-eight drugs seizures took place at the high-profile concerts, according to figures compiled by gardai.
The southside venue hosted a range of international acts this summer.
Arcade Fire kicked off the round of music events on June 29 and Kanye West followed on July 2.
British indie band The Arctic Monkeys also took to the stage at the Rathfarnham venue in July, as did Macklemore.
Gardai declined to break down the dates of the arrests, so it is not known which concert proved the worst for anti-social behaviour.
The use of the park for big-crowd music events was criticised by residents last month.
People living near the park contacted local councillors to complain about the impact concerts were having on the area.
Fine Gael's Neale Richmond said he received 150 complaints after the eight-night stint of concerts over June and July.
The use of the park as a music venue is to be reviewed by Dun Laoghaire-Rathdown County Council in the autumn.
Longitude festival took place over three days in the park and attracted around 20,000 music fans.
Anti-social behaviour at concerts has been of particular concern since the Swedish House Mafia gig at the Phoenix Park in 2012 saw a number of people stabbed.
Labour councillor Lettie McCarthy said: "If people are going to go to gigs and engage in anti-social behaviour, at least it is good to know that it will be dealt with."
