When Ireland’s the Cranberries first found fame in the early ’90s, their incandescent sweetness made them a nice contrast to all the fuzzed-out grunge that was running alt-rock radio at the time. But if recent allegations are true, Cranberries leader Dolores O’Riordan is way more of a hooligan than any of her flannel-bedecked contemporaries.

According to TMZ, O’Riordan attacked a flight attendant while she was on a flight from New York to Ireland recently. The woman she allegedly assaulted went to the hospital with a leg or foot injury. And when police boarded the plane to remove O’Riordan, she allegedly headbutted the officer who tried to arrest her. O’Riordan was arrested after being removed and taken to a hospital in Limerick. The BBC reports that O’Riordan has been discharged from the hospital and that she’s been released without being charged.
