DOLORES O’Riordan, lead singer of Irish band The Cranberries, has died suddenly.
She was 46.
O’Riordan died in London, where she was recording, publicist Lindsey Holmes said.
The cause of death wasn’t immediately available.
Holmes said the singer’s family is “devastated” by the news.
A statement from her publicist said: “Irish and international singer Dolores O’Riordan has died suddenly in London today. She was 46 years old.
“The lead singer with the Irish band The Cranberries was in London for a short recording session. No further details are available at this time.
“Family members are devastated to hear the breaking news and have requested privacy at this very difficult time.”
A police spokesman said: “Police in Westminster are dealing with a sudden death.
“Officers were called at 9.05am (8.05pm AEDT) on Monday to a Hotel in Park Lane. A woman in her mid 40s was pronounced dead at the scene.
“At this early stage the death is being treated as unexplained. Inquiries continue.”
O’Riodran last updated her Twitter account on January 3, posting a photo with her cat Gio, saying she was “off to Ireland”.
Formed in Limerick, Ireland, the Cranberries became international stars in the 1990s with hits including Zombie and Linger that fused the alternative rock edge with poppy tunefulness.
The band split up in 2003 but reunited several years later.
They released the acoustic album Something Else in 2017 and had been due to tour Europe and North America, but the tour was cut short because O’Riordan was suffering from back problems.
On December 20 the singer tweeted from the band’s official account, writing: “Hi All, Dolores here. Feeling good!
“I did my first bit of gigging in months at the weekend, performed a few songs at the Billboard annual staff holiday party in New York with the house band. Really enjoyed it! Happy Christmas to all our fans!! Xo”
Last year she revealed that she had been diagnosed with bipolar disorder in 2015, having battled with depression during much of her career.
“There are two ends of the spectrum – you can get extremely depressed and dark and lose interest in the things you love to do, then you can get super manic,” she told Metro.
“I was at the hypomanic side of the spectrum on and off for a long period but generally you can only last at that end for around three months before you hit rock bottom and go down into depression.
“When you’re manic you don’t sleep and get very paranoid. So I’m dealing with it with medication.?
In 2014, O’Riordan was accused of assaulting three police officers and a flight attendant during a flight from New York to Ireland. She pleaded guilty and was fined $9000.
The Cranberries had two No.1 albums in Australia, 1994’s No Need to Argue and 1996’s To The Faithful Departed.
They were perhaps best known for the 1994 single Zombie, which topped the ARIA charts for eight weeks as well as the Triple J Hottest 100 for that year.
It was also sampled on rapper Eminem’s recent chart-topping album Revival.
The Cranberries’ most recent Australian tour was in 2012.
