Cranberries singer Dolores O'Riordan spent three hours singing and shouting in a jail cell at Shannon Garda Station yesterday, it has emerged.
The singer was detained for three hours after an alleged air-rage incident onboard an Aer Lingus transatlantic flight yesterday.
The 43-year-old was arrested and questioned at Shannon Garda Station in the early hours of Monday in relation to a Section 3 Assault, which took place on a flight from New York to Shannon.
The mum-of-three's chorus of song from the jail cell took place after she was arrested at the airport shortly before 5am.
Sources said her behaviour during the time in the cell eventually resulted in the gardai calling a local doctor out of concern for Ms O'Riordan's psychological well-being.
She was later treated in University Hospital Limerick (UHL) and then released into the care of her family yesterday.
The singer and former Voice of Ireland mentor must now await the decision of the Director of Public Prosecutions on whether she will face charges.
At the O'Riordan home yesterday, the family declined to comment on the matter.
The incident on board the flight from New York, which had 118 people on board, resulted in an assault on a flight attendant and on a garda who was called to the scene.
The singer was taken from the plane and brought to Shannon Garda Station for questioning. She was later brought to University Hospital Limerick (UHL) at 10am yesterday after she was assessed by a doctor while in garda custody.
She was released from hospital shortly after 3.30pm into the care of her mother, Eileen.
Gardai confirmed Ms O'Riordan had left garda custody. A file will now be prepared for the Director of Public Prosecutions in relation to the incident.
The incident also resulted in the hospitalisation of the flight attendant, named locally as Carmel Coyle.
She underwent x-rays at UHL to assess the damage to her foot, which was believed to have been fractured in the incident. She was later released from hospital.
The garda officer didn't suffer any serious injury. The incident began in the early hours of Monday morning. Gardai were called to meet the EI-110 flight shortly before 5am after a passenger on the flight from JFK to Shannon had become disruptive.
However, the incident continued to escalate after one of the two gardai called to the scene was allegedly headbutted by the star. It is also alleged that she spat in his face.
Ms O'Riordan had been 'disruptive' on the flight prior to it landing in Shannon.
Upon boarding the flight, one passenger had tweeted: "So Delores [stet] 'Cranberry' O'Riordan just boarded our JFK/SNN flight wearing red & black Superhero mask" [sic].
The flight arrived in Shannon an hour and 20 minutes ahead of schedule at around 4.40am.
However, it was not able to disembark for 20 minutes until ground handling staff began work at 5am. It is understood the singer had left her seat and refused to sit back down.
The singer is then alleged to have stamped on the female flight attendant's foot. Gardai were requested to meet the flight and two officers boarded the plane.
While arresting the former Voice of Ireland mentor and bringing her to a waiting garda car, she allegedly head-butted a garda before spitting in his face.
One eyewitness said passengers became aware of the commotion when they saw a woman in business class standing up and shouting about 20 minutes before landing. When gardai boarded the flight the commotion continued.
"The curtains were opened a few times and at one stage we saw the woman thumping the ceiling of the plane," the eyewitness said.
"It was only after we got off the plane that we heard who it was."
A spokesperson for Aer Lingus confirmed that an incident took place on board and was being investigated by gardai.
Ms O'Riordan spends most of her time in the US and it is understood that she is back in Ireland for 14 days.
