Stewards examining new evidence...
Formula One officials are investigating Lewis Hamilton's victory in last weekend's Japanese Grand Prix, amid allegations that he engaged in improper driving, a FIA spokeswoman said Thursday.
Officials are reviewing video evidence
suggesting that Hamilton's driving behind the safety car at the rain-lashed Fuji Speedway led to a crash that ended the race for Mark Webber and Sebastian Vettel.
"New evidence has been brought to the stewards' attention and they are currently looking into the matter," said the spokeswoman for the FIA, the sport's governing body.
"It would be inappropriate for us to comment any further at this particular stage, in particular as to what penalty, if any, might be imposed."
The British rookie leads the race for the world championship by 12 points, with two races left. But if found guilty of improper driving, his points from Japan could be erased or - more likely - he could face a grid position penalty in Shanghai. Hamilton was expected to meet with Formula One stewards on Friday.
The incident was missed by official TV coverage, but a clip posted on the YouTube video sharing website shows Hamilton slowing dramatically and veering to the right of the track just before Vettel rear-ended Webber.
Vettel has been penalised ten grid positions at the Chinese Grand Prix for his role in the crash, and Hamilton could expect a similar punishment if found to be in breach of Formula One safety car regulations.
Webber and Vettel have both since been critical of Hamilton's performance.
