The 65-year-old tower crane operator was working in the Athletes Village. Early reports quoted an eyewitness seeing him slip while climbing down the ladder in torrential rain, falling 30ft and banging his head. He was found slumped in the stairwell at the foot of the crane and pronounced dead at the scene by an air ambulance doctor.
A post mortem examination later established that he suffered a fatal cardiac arrest. As the incident is therefore deemed not related to his work, the Health & Safety Executive will not be investigating any further.
Earlier this month the The Olympic Delivery Authority (ODA) reported that after three million working hours there had been no serious injuries. With more than 12,000 workers on site, the reportable accident rate is just a third of the industry average.
