Shane Warne had complained of chest pain and sweating after extreme fluid-only diet prior to his vacation: Manager

Shane Warne had recently complained of 'chest pain and sweating' after undergoing a ridiculous two-week fluid-only diet before he left for his vacation, the Australian spin legend's manager James Erskine has revealed.

Warne, a spin wizard who made the world fall in love with his craft, died at the age of 52 due to a suspected heart attack in Thailand on Friday, leaving the world shell-shocked.

"He did go on these ridiculous sorts of diets and he just finished one, where he basically only ate fluids for 14 days and he'd done this three or four times," Erskine told 'Nine Network.' "It was a bit all or nothing. It was either white buns with butter and lasagne stuffed in the middle or he would be having black and green juices.

The Thai Police on Sunday said that initial investigations have shown no indication of foul play in Warne's death but an autopsy has been conducted.

In an Instagram post a few days before his death, Warne had posted an old picture of himself in peak physical condition, announcing that he had started a weight-loss regime.

"Operation shred has started (10 days in) & the goal by July is to get back to this shape from a few years ago! Let's go #healthy #fitness #feelgood," he wrote.

According to the Koh Samui's Bo Phut police station superintendent Yuttana Sirisomba, Warne had "seen a doctor about his heart" recently.

Warne's family had also informed the Thai police about his history of heart problems and asthma and their concern about his health before he left Australia.

Warne along with his friends had reportedly travelled to the popular island of Koh Samui, situated in the Gulf of Thailand.

As per the local police information, one of Warne's friends found the Aussie legend unresponsive around 5pm.

The group commenced CPR on Warne while waiting for an ambulance.
