Formula One champion Lewis Hamilton risks being stripped of his German Grand Prix victory after being summoned by Hockenheim stewards on Sunday for a possible pit-lane infringement. Stewards were investigating whether the Mercedes driver, who won from 14th on the grid, illegally crossed a line separating the entry from the track when he hurriedly changed his mind about pitting during a safety car period.
Hamilton, who could be handed a time penalty if found guilty of the offence, finished 4.5 seconds ahead of Finnish team mate Valtteri Bottas and 6.7 clear of Ferrari's third-placed Kimi Raikkonen. Raikkonen collected a five-second penalty in Azerbaijan two years ago for a pitlane offence.
