The world motor racing champion Sebastian Vettel has led other Formula One drivers in paying tribute to a Canadian Grand Prix marshal who died after being run over by a mobile crane during Monday's race in Montreal.
The marshal died in hospital from injuries sustained while he was removing the Sauber of the Mexican rookie Esteban Gutierrez, who'd crashed out seven laps from the end of the race.
The International Automobile Federation said in a statement that the track worker had dropped his radio and attempted to pick it up. In doing so, he stumbled and was hit and run over by the recovery vehicle.
The former British driver Martin Brundle, now a TV commentator, had suggested before the accident happened that it might have been safer to leave the car where it was, rather than move it in a hurry.
