There were no arrests made at last night’s nervously-anticipated DJ Hardwell gig at Dublin’s The 02.
There were fears that last night’s concert would turn into a night of chaos after dramatic scenes at the DJ’s Belfast gig.
Security at the 02 were prepared for another night of unrest but Gardai have said, ‘‘there were no issues or arrests reported to us last night.’’
The use of class A drugs by teenagers at the Odyssey was blamed for sparking the Major Incident that led to 18 people being hospitalised.
Police launched an investigation into a mass underage drinking binge that saw more than 100 young concert-goers treated by medics in Belfast.
Children as young as 13 were so severely ill that they could not speak and their eyes were rolling into the backs of their heads.
The drugs which they admitted taking included heroin, ecstasy and so-called legal highs.
There was a higher concentration of people who were seriously ill in a short time period.
There were reports of a number of fights breaking out and widespread drug taking.
Three people were arrested during the course of the night - a man aged 21 was detained for disorderly behaviour, another aged 18 was arrested for assault and resisting police arrest, and a 16-year-old woman was arrested for assault and resisting arrest.
A major incident was declared by the Northern Ireland Ambulance Service and in two of the city's hospitals, where extra staff were called in to help.
Police said around 300 young people were refused entry to the premises - some of whom were drunk and others too young to gain entry to the 16-and-over gig.
Joe Hyland, chief executive of the SoS Bus, a charity that helps people who get themselves into trouble on a night out, was at the Odyssey on Thursday night as 10,000 people attended a DJ Hardwell concert.
He stressed that there were two different events – the concert inside, which he said was a success, and the chaos outside.
Mr Hyland said what caused the crisis was a combination of a very high concentration of casualties and the severity of the illness.
The charity had two buses and 23 volunteers, but was swamped.
"The event itself truly was successful but the overflow of the young kids that couldn't get in because they were underage or too drunk wasn't properly planned," he said.
He said inexperienced young drinkers led to high numbers of people who fell ill, but also said there was use of class A drugs.
"They have no idea about alcohol and how it affects them; 20% of the alcohol affects them in five to seven minutes and the other 80% goes into your small intestine and can take up to 45 minutes to affect you," he said.
