The future of the Brazilian Grand Prix at Sao Paulo's Interlagos circuit is this week clouded with uncertainty following the attempt by armed robbers to hijack the bullet-proof Mercedes limousine in which McLaren driver Jenson Button was travelling.

Jenson was being driven by an armed police driver who had been specially trained in defensive driving techniques. Also in the car were Jenson's father John, his manager Richard Goddard and his trainer Mike Collier. They stopped in a queue of cars at a set of traffic lights on the main road outside the Interlagos track  when the potential assailants emerged from the shadows.

The driver made good his escape, ramming several other cars as he energetically cleared a path through the tightly packed traffic to get his VIP cargo back to the hotel in one piece. Button described him as "brilliant, a legend."
