Singer 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 on November 10 last year following a flight 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 receiving ongoing medical treatment and presently she's receiving residential treatment, hence her absence from court," he said.
Mr O'Donnell said O'Riordan continues to benefit from the treatment and requested 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.
Ms O'Riordan is also facing being charged with resisting/wilfully obstructing Garda Shane Dawson in the execution of his duty contrary to Section 19 of the Criminal Justice (Public Order) Act 1994.
All of the alleged offences are said to have taken place after Ms O'Riordan left an Aer Lingus aircraft that had just landed from New York's JFK.
In court yesterday, Mr O'Donnell praised the work of Sgt John McCabe and other gardai in being very forthcoming with disclosure of evidence, saying that he has received statements in the case.
There was no legal obligation for Ms O'Riordan to be in court yesterday.
O'Riordan, from Friarstown, Kilmallock, Co Limerick, became a multi-award-winning musician as 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 with ex-husband Don Burton.
O'Riordan appeared as a mentor in RTE's The Voice talent show series but called it quits deciding that the commute from her Canadian hometown to Dublin was just too much.
