Australian cricket great Shane Warne died of natural causes, according to the autopsy report.

Warne was found unresponsive in his villa in Thailand last Friday at the age of 52 following a suspected heart attack.

His death rocked the sport, with tributes pouring in from across the world for the legendary spinner, who took 708 Test wickets across a 15-year career – second only to Muttiah Muralitharan.

Thai police previously claimed Warne had complained of chest pains prior to his passing, and they have since confirmed he died of natural causes.

In a statement on Monday, deputy national police spokesperson Kissana Phathanacharoen said: "Today investigators received the autopsy result, in which the medical opinion is that the cause of death is natural.

"Investigators will summarise the autopsy result for prosecutors within the timeframe of the law."

Songyot Chayaninporamet, deputy director of the hospital where Warne was taken, put the death down to a "congenital disease".

Songyot added: "There is no COVID-19 infection and no sign of assault or murder."

Warne's body is due to be returned to Australia on Tuesday, where he is to receive a state funeral in Victoria.
