Lotto winner, 73, drops dead just weeks after scooping £26m jackpot as doctors fear ‘shock of prize weakened his heart’

A LOTTO winner who scooped a £26 million prize has died after a massive heart attack just weeks after his record-breaking win.

Cattle rancher Antonio Lopes Siqueira, 73, collapsed during a routine dental appointment in Cuiaba, in the state of Matto Grosso, Brazil on December 4.

Siqueira had won the life-changing sum of £25.7 million in the country’s Mega-Sena draw on November 9.

Police are investigating after the coroner could not immediately identify the cause of death.

Further tests will determine whether Antonio had an existing heart condition, had been suffering from shock due to his huge win, or was murdered.

Antonio was attending a routine dental appointment when he collapsed in the waiting room.

An autopsy discovered that the father of four had suffered a massive cardiorespiratory arrest, but this has not been confirmed as his cause of death.

Antonio is also thought to have suffered from high blood pressure and diabetes.

His recent win, from a lucky dip game, was one of the 10 highest prizes in the history of the Brazilian lottery
