An 18-year-old girl is in a critical condition following a crush on Harcourt street in Dublin last night.
The incident happened shortly before midnight at Camden Place and Harcourt Street where a crowd of up to 1,500 had gathered to attend an event at popular nightspot Copper Face Jack's.
Seven people were injured in a crowd surge. Four attended Accident and Emergency departments, while an 18-year-old girl is in a critical condition.
Gardaí are investigating the incident.
The owner of Copper Face Jack's, Cathal Jackson, told the Irish Independent he was aware of the incident and arrived on-scene just before midnight.
“It was the first time we actually had an over 18s specifically on a Monday night,” he said.
The event, called "Messy Mondays" had been advertised as the first over-18s event at the club, which is usually over-21s.
It had been advertised on Facebook as "guaranteed to be busy" with drinks costing €3.50.
One commenter on the Facebook event early this morning said "messy night was the right title," while another labelled the event "a disaster".
Copper Face Jack's said it is working closely with authorities to establish the cause of the incident.
