Vettel digs in to deny Bottas in thriller

Sebastian Vettel held off a thrilling late challenge from Valtteri Bottas to win the Bahrain Grand Prix and extend his lead over Lewis Hamilton at the World Championship summit.

Hamilton, who started only ninth, completed the podium places after Kimi Raikkonen retired following a nasty collision with one of his own mechanics during a pit stop.

The mechanic was knocked down and taken to the medical centre to be assessed in an incident which was not out of place during a chaotic race under the floodlights of the Sakhir circuit.
