A welder in the UK found dead in his bedroom by his housemates had overdosed on caffeine, a coronial inquest has heard.
Polish national Lukasz Sandelewski, 36, had a blood-caffeine concentration of 282 micrograms per millilitre, more than three-and-a-half times what would be considered a fatal dose.
His housemates found him dead in December last year after receiving a concerned Facebook message from his mother, who was having trouble reaching him.
His room in the town of Peterborough was cluttered with “lots of empty drinking vessels”, assistant coroner Sean Horstead told the coronial inquest.
But the inquest concluded that it is not known how he had consumed so much caffeine.
His cause of death was listed as “misadventure”.
“His death was the unintended consequence of a deliberate act,” Mr Horstead said.
