He said a post-mortem examination has been conducted "and the court is awaiting the results of various tests that have been commissioned."
Police say they don't consider the death suspicious, meaning they have found no sign of foul play.
The Cranberries formed in the Irish city of Limerick at the end of the 1980s and had international hits in the '90s with songs including "Dreams," ''Linger" and "Zombie."
