[Nepali labourer Rupchandra Rumba] had been working... at the Education City football stadium, a new 40,000-seat arena set to host a World Cup quarter-final...

his sudden and unexplained death was attributed to “acute cardio respiratory failure due to natural cause[s]”...

which the World Cup organisers call, “non-work related deaths”.

Deaths from natural causes are never investigated... [although workers] can be exposed to hours of extreme heat stress every day for months at a time over the summer. Cardiologists now say that heat stress is the direct cause of the high numbers of deaths attributed to cardiovascular problems in Qatar.
