Indiependence festival organisers are warning festivalgoers about a "bad batch of something" going around.
The Mitchelstown, Co Cork festival put out a message on its official Twitter account warning of the substance at around 9:30pm tonight.
The nature of the substance is not currently known, but people are being asked to refrain from taking anything they are unsure of, Cork Beo reports.
Organisers also ask that punters look after one another.
A festival spokesperson said: "Welfare Message - We have reports of a bad batch of something in the campsite, do not consume any substances that you are unsure about, it has the potential to make you very sick.
"Please be careful and look after each other."
We currently have no reports of anyone being removed from the concert as a result of sickness, but we are looking into the situation.
Bastille is headlining tonight on day one of the festival, with Lewis Capaldi in the supporting role.
