The Prodigy singer Keith Flint has been found dead at his home in England.
The 49-year-old took his own life, the band said in a statement.
He was found by police on Monday morning after emergency services were called to reports of a man who had fallen unconscious.
His death is not being treated as suspicious.
Flint featured on a host of The Prodigy’s most famous hits – including 'Breathe' and 'Firestarter'.

In a statement on Instagram, the band said: "The news is true, I can’t believe I’m saying this but our brother Keith took his own life over the weekend, I’m shell shocked, fuckin angry, confused and heart broken ..... r.i.p brother Liam #theprodigy".
An Essex Police spokeswoman said: “We were called to concerns for the welfare of a man at an address in Brook Hill, North End, just after 8.10am on Monday,” said an Essex police spokesman in a statement.
"We attended and, sadly, a 49-year-old man was pronounced dead at the scene. His next of kin have been informed. The death is not being treated as suspicious and a file will be prepared for the coroner."

The Prodigy emerged from the underground rave scene of the early 1990s.
Flint, who was always instantly recognisable for his spiked hair and unique style, was initially a dancer with the band before moving to sing on 'Firestarter' and 'Breathe'.
The singles from their third album, The Fat Of The Land, propelled them into the mainstream.
Both the singles and the album topped the charts, achieving multiplatinum sales.
Six of their seven albums reached number one, with their last, No Tourists, released in November last year.
They are estimated to have sold about 30 million records across the world.
Emily Eavis, co-organiser of Glastonbury Festival, posted to reveal The Prodigy had been due to play this year's festival.
"We are so saddened to hear the news about the passing of Keith Flint," she said.
"He's played here so many times over the years with the Prodigy and was booked to play this year. What an incredible frontman, he gave us all so much life and energy," she added.
Ed Simons, of The Chemical Brothers, was among those paying tribute, tweeting: "Oh gosh, so sad to hear about Keith Flint, he was always great fun to be around and very kind to Tom and I when we first started doing shows together.. great man."
