More than 50 ravers were packed into a Halloween party allegedly organized by health workers.
Revelers have come under fire after the Dublin incident that ignored coronavirus restrictions.
Footage obtained from Dublin Live shows the student clubbers in a small room that dances from late Saturday evening until the early hours of the morning on Sunday.
The big meeting organizer is said to be a frontline worker caring for elderly patients in Dublin.
Ravers post several videos and pictures on social media platforms during the all-nighter event.
Other videos show bags of what appears to be a white substance being placed on tables and lined up.
A source said: “This has been described as a ‘drug-fueled’ event that reportedly attended over 50 Brazilian students.
“And what’s worse, it was all organized by health workers who take care of the elderly.
“Neither the organizers nor the participants hid it.
“Many have posted clips and pictures on social media, some of which showed drug use.”
A native Brazilian who lived in Dublin for almost eight years received the videos in a WhatsApp group but immediately called the Gardai.
She told Dublin Live, “The videos were broadcast to a private group that I am in and everyone seemed crazy about them.
“I just couldn’t see it and kept calm. It’s not fair to everyone else. I have a child who hasn’t seen his grandparents since March. I haven’t seen my friends since then.”
“I did a little more research and found it was all over Instagram and Facebook, they had no shame.”
She added, “That is why I am currently unemployed. You try your best to survive and then you see things like this happening. It is not right.”
