The toxicology report issued by the Czech hospital where Mr Pádraig McNally was treated shows traces of a sedative in his body, a report on RTÉradio said today.
The report revealed traces of benzodiazepines, a type of sedative normally found in Valium and often used to relieve anxiety primarily as sleeping tablets.
When taken in large doses it slows down breathing and can cause cardiac arrest.
The report adds credence to the theory that Mr McNally and his friend Mr Michael O’Leary, who was later found dead in a park, had their drinks spiked as part of a fatal robbery carried out by local criminal elements.
Mr Michael O’Leary’s death was initially described as self-misadventure by the Czech police.
The two men were taking part in a Macra na Feirme-sponsored trip to Prague.
