As the sun rose at about 5am Sunday morning at a dance in Winthorn, Westmoreland, patrons grew angry as the much anticipated deejay scheduled to perform did not show up began hurling bottles and stones at the stage.
As the anger escalated, persons affiliated with the staging of the dance joined in the melee and many artists and promotors were said to have been beaten.
One witness recounted that he saw bloodied faces and broken limbs.
Deejay Einstein, who had performed at the dance, admitted to hearing rumours that the beatings had been ordered.
The Whithorn police say that while they have heard of the incident no details were forthcoming and they have not received a formal report.
The "no-show" deejay is yet to make a statement.
