Cranberries frontwoman Dolores O'Riordan has spoken about her arrest following an incident on board an Aer Lingus flight last week and says she is dealing with "demons" since her separation from husband, Don Burton.

The Voice of Ireland mentor was arrested and taken to a police cell in Clare after a fracas following the landing of an early morning flight to Shannon from New York. 

Speaking to the Sunday Independent, she said: "Apparently my mother came into the cell. I don’t remember. I had created a tortoise effect. I tucked myself in, under the blanket. I was singing in the cell. I was praying. I was meditating because I was freezing."

The 43-year-old singer says she was not drunk on the flight and added that she is dealing with "demons" since she legally separated from her husband Don Burton.

She also apologised to Aer Lingus attendant Carmel Coyne, who suffered injuries to her foot during the incident when the flight landed at Shannon last Monday morning.

"Carmel is lovely. I know Carmel a long time from flying over and back transatlantic since I had the little wee babies in the buggies. I really like her," O'Riordan said. 

"She knows, for a fact, that it was an accident with my metal shoes. And there was bad people having too much booze roaring at me.

"And I backed up and I stood on her foot by an accident, like a child in the playground. I’m sorry, Carmel. You know I love you and if there is any way I can help you, I’ll be there for you."
