Flint has died aged 49, and was found by Essex police who were called to perform a welfare check at his home in Essex.
His cause of death has not been officially confirmed; however, his bandmate and friend Liam has told fans that Keith took his own life.
In a post on the band’s official Instagram account, Howlett wrote: ‘The news is true, I can’t believe I’m saying this but our brother Keith took his own life over the weekend.
And on twitter The Prodigy wrote;
It is with deepest shock and sadness that we can confirm the death of our brother and best friend Keith Flint. A true pioneer, innovator and legend. He will be forever missed.
We thank you for respecting the privacy of all concerned at this time.
‘I’m shell shocked, fuckin angry, confused and heart broken ….. r.i.p brother Liam.’
This comes after The Prodigy issued a statement, reading: ‘It is with deepest shock and sadness that we can confirm the death of our brother and best friend Keith Flint.
‘A true pioneer, innovator and legend. He will be forever missed.
‘We thank you for respecting the privacy of all concerned at this time.’
Essex Police confirmed Flint’s death, saying: ‘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.
‘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.
Flint’s last performance with The Prodigy was on 5 February, when the dance act played at The Trusts Arena in Auckland, New Zealand.
They were set to headline London’s SW4 festival, which takes place on Clapham Common on 24 and 25 August.
Keith’s final vocals for the band can we heard on the track We Live Forever from the group’s seventh album, No Tourists, which was released just five months ago.
A rep for Keith declined to comment.
