Lewis Hamilton is under investigation by Formula One officials over his behaviour at Sunday's Japanese Grand Prix.
The world championships leader was accused by Red Bull driver Mark Webber of causing him to hit Toro Rosso's Sebastian Vettel by speeding up and slowing down behind the safety car.
An FIA official said: ‘We understand the stewards of the meeting have received new evidence and are looking into the relevant matter.
‘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 evidence is believed to be footage from video website YouTube, which was filmed from the grandstands at Fuji.
It appears to show Hamilton decelerating dramatically on the right of the track, forcing Webber to slow down and catch Vettel unaware.
Webber said: ‘It definitely contributed to Sebastian hitting me up the back because he (Hamilton) wasn't doing what he was supposed to be doing, clearly.
‘He spoke in the drivers' meeting about how good a job he was going to do and he did the opposite. Still, we know for next time.’
The collision occurred on lap 45 when Webber almost overtook Hamilton before an unsighted Vettel hit him.
F1 regulations state the leader must keep a within five metres of the safety car, while erratic driving can also be punished.
Article 40.10 of the F1 Sporting Regulations reads: ‘The safety car shall be used at least until the leader is behind it and all remaining cars are lined up behind him. Once behind the safety car, the race leader must keep within five car lengths of it.’
It is thought Hamilton has already met a three-man panel of stewards at the Chinese Grand Prix in Shanghai.
They are believed to be deliberating on what action to take over the incident.
If he found guilty of dangerous driving, Hamilton could have his points from the Japanese race wiped out.
That would be a huge blow to his hopes of becoming the first driver to win the world championship in his rookie season.
His Fuji victory gave him a 12-point lead over defending champion and team-mate Fernando Alonso.
If he does not receive a points deduction, he could seal the title on Sunday.
The most likely punishment, if any, appears to be a ten-place grid penalty at Sunday's Chinese Grand Prix.
German driver Vettel claimed he too was distracted by Hamilton's behaviour.
‘It was my fault, but it is clear the rhythm was not there,’ he said.
‘We are all sitting in the same boat. At that point (of the crash) I was distracted, looking to the right.
‘I was sure Hamilton was retiring, he seemed to have no power any longer, but by the time I looked back, I was already in Mark's rear end.’
