GARDAI had to be called to restore order at a popular beach after a large gathering of youths threatened to turn violent.
Up to 1,000 people, many of whom were teenagers beginning their summer holidays, assembled on the grassy dunes above Portmarnock Beach, North Dublin to enjoy the sunshine.
However, the scene descended into chaos in the late afternoon after some of them had consumed beer and other alcohol.
A number of garda units travelled to the area, to bring order to the melee and a Garda EC-135 helicopter kept watch from overhead.
Gardai on the ground confiscated alcohol from those who were underage and remained in the area to ensure that trouble did not erupt.
A garda spokesman said there were no arrests and no one was hurt.
“It was a public order incident,” he said.
However the sheer numbers gathered proved to be intimidating to families, with small children who had come down to the beach to sunbathe and swim.
In a separate incident, Irish Rail confirmed that its 16.14 Drogheda to Pearse service had to stop at Portmarnock because a group of young people on board the train were causing problems for the driver, and other passengers.
A press officer said the youths were drinking and being unacceptably rowdy - Irish Rail's security team contacted the gardaí, who attended and removed the offenders. The train was delayed for 10 minutes.
Ireland manager Giovanni Trappatoni narrowly missed being caught up in the beach melee.
The Ireland manager had been with the Irish squad at their Portmarnock Hotel base before he decided to get some air.
