The mother of Dolores O’Riordan, who was arrested on Monday morning after an alleged air rage incident, has revealed that her daughter has split from her husband of 20 years. During an interview with the Limerick Leader, Eileen O’Riordan explained that her daughter is going through a difficult time and is "under the care of a psychiatric doctor." She explained: "She is going through a marriage separation at the moment. That's hard for anyone." Dolores married Don Burton, former tour manager of Duran Duran, back in 1994. They have three children– Taylor (16), Molly (13) and Dakota (9) – who are currently with their father in Canada. Dolores O'Riordan is best known for being in The Cranberries. Eileen described the moment she saw her daughter at Shannon garda station following the arrest: “Dolores was inside in a room, she was lying on the floor, curled up. She had her head covered and her face covered up. "She was trying to protect herself. I gave her a hug. I tried to talk to her. She didn’t realise I was there at all. I put Lourdes water on her… She didn’t know who I was, she was trying to cover herself from me." As for the incident itself, Eileen believes that Dolores was provoked: "She had two glasses of wine with her dinner when she started off but she had no alcohol or drugs in her system. That is completely clear. "She was accompanied by a producer and songwriter. I believe there were people hassling her to sing and for photographs on the plane. She just lost it." Earlier this week it was reported that The Cranberries singer (43), who was later released without charge, had assaulted an air hostess and garda during an air rage incident.
