Dolores O’Riordan is receiving medical care as she awaits trial over an alleged air rage incident, a court has heard.

The Cranberries singer is facing four charges including assault after being arrested at Shannon Airport in Ireland on November 10 last year after flying in from New York.

O’Riordan’s solicitor Bill O’Donnell revealed her treatment as he asked for the case at Ennis District Court in Co Clare to be adjourned for three months.

“My client is presently receiving ongoing medical treatment and presently she’s receiving residential treatment, hence her absence from court,” he said.

Mr O’Donnell said O’Riordan would benefit from a delay in the case.

The 43-year-old is charged with three assaults and one offence of wilful obstruction of a Garda.

Judge Patrick Durcan agreed to the adjournment, saying: “If the person is having treatment then I think we should facilitate that.”

The case will be back before Ennis District Court on December 16 for a plea to be entered or a date for a hearing to be set, the court was told.

The alleged incident began in the business section of Aer Lingus flight EI 110 from JFK Airport shortly before it came in to land in Shannon.

O’Riordan, from Friarstown, Kilmallock, Co Limerick, is renowned for her distinctive singing voice.

She became a multi award-winning musician after becoming lead singer of the Cranberries when she was just 18. They went on to be one of the biggest bands of the 1990s, selling tens of millions of records.

She has three children.
