Fernando Alonso has warned Lewis Hamilton to cut out the rough stuff or face the consequences.

The Spaniard said that if the 25-year-old British star repeats his antics in Malaysia and China he could be kicked down the grid or even booted out of the race.

Hamilton charged down the pit lane side by side with Sebastian Vettel in Shanghai and weaved in front of Vitaly Petrov in Sepang.

And Alonso, Hamilton's former McLaren team-mate who is now at Ferrari, said: "I don't think Hamilton is in any kind of privileged position.

"The decisions have been inconsistent, because at other times Hamilton would have been punished.

"Lewis has had some warnings and if he does something in the next race, however little, there will be penalties because of the last two races."

But GP legend Sir Jackie Stewart believes that Hamilton's stirring performances have ruffled feathers. "He has woken up a lot of drivers with his skills," said Stewart.

"I don't think he is dangerous. He has got a lot of enthusiasm but he has to realise that can induce judgments you otherwise might not make. That is part of the maturing process."
