Six people were rushed to hospital after an incident on a funfair ride in Carrickfergus, Co Antrim, yesterday.
Emergency services were called to the scene shortly before 6pm after they received reports that a ride had collapsed.
Three children are among those taken to hospital but it is understood none of those hurt in the incident have life-threatening injuries.
A number of other children suffered injuries to their legs, but did not require hospital treatment.
