Cranberries singer Dolores O’Riordan, 43, has been receiving “on going” medical treatment and is said by her solicitor to be too ill to attend her court date.

She is facing four charges which include assault after she was arrested last year. In November 2014 she was arrested in Shannon Airport following a flight from New York.

She is also being charged with one offence of wilful obstruction of a Garda.

The Independent reported that concerns had been raised for Dolores when she was taken into custody and was then “engaged in a chorus of singing and shouting from her jail cell.”

Her solicitor Bill O’Donnell told Ennis District Court that she has been receiving residential medical treatment and would be able to make an appearance.

He asked for the case to be adjourned for three months and added that Dolores would “benefit” from the delay. He said:

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

Judge Patrick Durcan has agreed to the adjournment and adding that if someone is need of medical treatment he believes the court “should facilitate that.”

Shortly after the incident, it was revealed that the mother of three was in the middle of separating from her husband of 20 years Don Burton.

Her mother Eileen explained:

“She is going through a marriage separation at the moment; that’s hard for anyone.”

She also added that she was concerned for her daughter’s health at the time, adding that she had hoped her daughter would return from New York in good health.

“She wouldn’t have the support there. She is suffering from lack of sleep over the weeks and her brain is racing all the time. She is working very hard. When she was in New York she kept saying ‘when I go home to my mother in Ireland, I will be fine.”
