A volunteer track worker at the Canadian Grand Prix died Sunday after being run over by a crane removing a car from the course after the checkered flag.
The man, who wasn't immediately identified, died after being taken by helicopter to a hospital.
"The worker was helping to recover a car, which had stopped during the race," F1 spokesman Matteo Bonciani said. "The recovery vehicle had lifted the car to return it to the pits and while doing this the worker dropped his radio and attempted to pick it up. As he did this, he stumbled and was hit and run over."
Race promoter Francois Dumontier said the man was about 38 years old.
"It's terrible," Dumontier said. "It tarnishes the superb weekend that we had. I am devastated to learn this. I don't have any other words."
