Hamilton under investigation over Japan driving

Formula One stewards in Shanghai are examining new evidence concerning Lewis Hamilton’s driving behind the safety car in last weekend’s rain-swept Japanese Grand Prix.

The McLaren star was leading the pack awaiting a restart when the two cars immediately behind him - Mark Webber’s Red Bull and Sebastian Vettel’s Toro Rosso - collided, putting both out of the race.

Webber and Vettel both hinted that erratic driving from Hamilton had played a role in their shunt. Video footage is understood to show the championship leader moving to the right of the track and slowing immediately prior to the accident, in which Vettel ran into the back of Webber's car.
