Fox Sports television, which employed Warne as a commentator, quoted a family statement early Saturday as saying he died of a suspected heart attack in Koh Samui, Thailand.
“Shane was found unresponsive in his villa and despite the best efforts of medical staff, he could not be revived,” the statement said. “The family requests privacy at this time and will provide further details in due course.”
Police in Thailand said Warne’s body was transferred to Ko Samui Hospital for an autopsy. Police added they did not find any wounds on Warne’s body.
Known as “Warnie,” Warne took 708 test wickets in 145 matches for Australia from 1992-2007, second only to Sri Lanka great Muttiah Muralitharan’s 800 test wickets from 133 matches.
“Spinning was a dying art, really, till Shane Warne came along,” cricket commentator Jonathan Agnew told the BBC.
Warne was also part of five Ashes-winning teams against England during his career.
Warne made his test debut at the Sydney Cricket Ground in 1992 and rose to become a key figure across all formats in one of the greatest sustained periods of dominance by any team in world cricket.
